Shola-grassland mosaic in danger Strobilanthes dyerianus ( Persian Shield) is a tropical plant native to Myanmar. It grows up to 2 M. It belongs to the Acanthaceae family. This difference in the number of visits between the first and second day was highly significant (Mann–Whitney U = 5.30, P = 0.0001). Strobilanthes kunthiana, kurinji or neelakurinji, is a shrub that is found in the shola forests of the Western Ghats in South India. If S. kunthianus happened to be self-incompatible, its reproductive success would have been significantly reduced because of the prevalence of geitonogamy and the resulting interference of self-pollen. The plant Neelakurinji (Strobilanthes kunthiana) flowers once in every 12 years. The term was first used by Alphonse de Candolle.Other terms with the same meaning are hapaxanth and semelparous.The antonym is polycarpic, a plant that flowers and sets seeds many times during its lifetime; the antonym of semelparous is iteroparous.Plants which flower en masse (gregariously) before dying are known as plietesials. According to the life cycle, plants can be divided as annuals, biannuals and perennials. 2. Strobilanthes carmelensis, a plietesial new species apparently ascribable to the Strobilanthes kunthiana-group, is described for the flora of Western Ghats (India, Wayanad District, State of Kerala). A long-lived gregariously flowering semelparous plant is even more committed to this single event because all of its kin will flower and die at the same time. Observations of immobilized bees showed a considerable number of pollen grains on the lower surface of the body in addition to the two pollen baskets. I try to time perennials so that germination occurs between mid-January and mid-March (earlier for the ones that are slow to grow, later for the growth engines. This curvature cycle of the stigma occurs irrespective of the pollen load and also continues on the second day. Our observations clearly show that pollinators visit the flowers on the second day, although the number of visits is much lower than on the first day. 7); the activity declined towards the evening. Monocarpic plants die after flowering and fruiting. Mean foraging visits of Apis cerana indica for pollen (filled bars) and nectar (open bars) during the day (mean ± standard deviation). Pollen viability was assessed through fluorescein diacetate test (Heslop-Harrison & Heslop-Harrison, 1970). This spectacle takes place only once in 12 years. However, in S. kunthianus, reproductive synchrony, attracting an adequate number of pollinators, together with other floral traits facilitating pollination resulted in a very high level of pollination efficiency. It means that flowering and fruiting only occurs once in the life span of this plant. 4). It also produces pale purple blooms, though rarely. As the pollen was heavily foraged during the morning hours, there was hardly any left in the afternoon on the first day of opening. = 7, N = 98), P = 0.0001] revealed a significant difference in nectar amount across time intervals. Semelparous or monocarpic species are perennial flowering plants that flower once in their lifetime and die. Why Strobilanthes Kunthiana is in the news? Leaves 3). A considerable proportion (60%) of pollen grains also remain viable on the second day, although this may not be a critical factor for pollination as the bee can bring viable pollen from its visits to fresh flowers. The stigma in these species is bilobed and the two lobes spread out at about 180° in fresh flowers. data). Strobilanthes dyerianus, native to Myanmar, is commonly called Persian Shield and is prized for its interesting foliage, dark green with metallic purple stripes radiating out from the center of the leaf. In another experiment, the visits of A. cerana indica to the same set of flowers on the first and second day were monitored. Examples: Rice, Wheat, Radish, Carrot, Bamboo, […] STROBILANTHES ATTENUATA SEEDS - Plant World Seeds. Monocarpic plants flower only once in their life. With the area under the plant fast diminishing owing to the denudation of land for cultivation, mass migration of jungle fowl has not been seen in recent years. Very few mono-carpic fruits are perennial. The flow of underground, perennial waters from the Sri Harishankara Temple is now contaminated with ore particles. The number of ovules in each ovary was counted through dissections under a stereomicroscope. Monocarpic plants are those that flower, set seeds and then die.. The viability decreased steadily during the second (57.8 ± 17%) and third (37.4 ± 19.9%) days, and was lost completely by the fourth day. She is a graduate of UCLA, where she majored in Flower buds were bagged before they opened to prevent insect visitation. Perennials live for more than two years and usually flower every year and set seeds. ADVERTISEMENTS: 2. Bagged flowers were excised at 4-h intervals (N = 10 at each interval), starting from flower opening until 18.00 h on the first day, and again from 06.00 to 18.00 h on the second day, and the quantity of nectar was measured. Strobilanthes Kunthiana. Strobilanthes ciliata is non-semelparous and the stigma is not sensitive to touch (M. V. Sharma, G. Kuriakose and K. R. Shivanna, unpubl. Pollen limitation (inadequate quantity or quality of pollen deposition on the stigma for optimal fruit and seed set) is quite common in flowering plants (Burd, 1994; Dudash & Fenster, 1997; Wilcock & Neiland, 2002; Knight et al., 2005). These plants are generally annual or biennial. Semelparous plants hav… The extension of floral longevity for 2 days enables pollination on the second day of flowers that remain unpollinated on the first day. Strobilanthes are mostly erect half-shrubby plants cultivated for their flowers and foliage. Its purplish blue flowers bloom once every 12 years. Strobilanthes is a genus of perennial flowering herbs and shrubs with about 250 species, at least 46 of which are native to India. Several species of Strobilanthes (Acanthaceae) distributed in the Indian subcontinent and South-East Asia are also semelparous and flower at intervals of 3–12 years. Jun 22, 2014 - Flickr is almost certainly the best online photo management and sharing application in the world. For studies on floral morphology, details of the floral whorls were studied and all the floral parts were measured (N = 25). For this, the flowers (N = 20) were tagged in the morning of the day of opening and kept under continuous observation (30 min pulse at each hour) for bee visits from 06.00 to 18.00 h on the first and second day of opening. A very high proportion of fruit set was observed in all pollination treatments. The curved, tubular violet flowers are produced over a long and valuable flowering season - usually until October or even later. According to earlier reports, mass flowering of this species attracted a large number of jungle fowl to feed on the large quantity of seeds produced (Matthew, 1971; Janzen, 1976). ADVERTISEMENTS: Some of the differences between monocarpic plants and polycarpic plants are as follows: Monocarpic Plants: 1. The evolution of the adaptive floral traits has facilitated mast seeding in the species. In another experiment, A. cerana indica visits to the same set of flowers were recorded from 06.00 to 18.00 h on the first and second day. S. dyerianus is one of the most commonly cultivated Strobilanthes species. The stigma in S. kunthianus is sensitive to touch by the pollinator and removes the receptive surface away from the path of the exiting pollinator. A welcome newcomer is this dwarf relative of Strobilanthes atropurpurea. It is a soft-stemmed, tropical, evergreen shrub or subshrub that is grown primarily for its attractive iridescent purple foliage. The reproductive strategies of S. kunthianus were investigated during its flowering season in 2006 in order to answer the question: how does the floral biology of S. kunthianus serve to prevent catastrophic reproductive failure? However, polycarpic plants flower and set seeds many times during its lifetime while monocarpic plants flower only once and die. Freshly opened flowers to show the position of the stigma in an undisturbed virgin flower. The anthers are bilobed and each anther produces 2880.3 ± 659.4 pollen grains. Studies on bamboos have not involved controlled pollinations and thus no conclusions can be drawn on the breeding system. The blooming season draws a large number of pollinators, including butterflies, birds, and bees. Strobilanthes dyerianus, commonly called Persian shield, is native to Burma (Myanmar). Strobilanthes Blume is the most species-rich genus of ... & Scotland 2000), the Strobifanthes kunthiana group (Carine et al 2004), the S. pentstemonoides group (Wood ... Perennial undershrub of unknown height, not or only weakly anisophyllous. This ceremony is followed by a victory dance and feasting. The corolla is tubular and five lobed at the tip; it measures 2.94 ± 0.12 cm in length. Photo: Godwin Vasanth Bosco. Strobilanthes kunthiana Small bluish violet campanulate flower with one side of the corolla slightly swollen from the base; set in dense broad bracted spikes. The flow of underground, perennial waters from the Sri Harishankara Temple is now contaminated with ore particles. To assess seed set under open pollination, 100 flowers were tagged randomly and kept under observation for fruit development. Its bright purple flowers bloom once every eight years, between July and September. Figure 9 presents the results. This movement orients the stigma, particularly the receptive surface, away from the path of the exiting bee (Fig. Strobilanthes kunthianus flowered during August–October 2006 (Fig. Each ovary bears four ovules. A. dorsata also carried some pollen on its legs. ... known long interval species, the Kurinji has been the most studied. A sample of foraging insects was collected using a sweep net, and the insects were immobilized by transferring them to a vial containing a piece of filter paper dipped in ethyl acetate. Strobilanthes Blume is the most species-rich genus of ... & Scotland 2000), the Strobifanthes kunthiana group (Carine et al 2004), the S. pentstemonoides group (Wood ... Perennial undershrub of unknown height, not or only weakly anisophyllous. A perennial herb or subshrub with numerous erect quadrangular stems.Blossoms gregariously once in 12 years. Find help & information on Strobilanthes kunthiana from the RHS All quantitative values are represented as the mean ± standard deviation. Strobilanthes kunthiana, kurinji or neelakurinji, is a shrub that is found in the shola forests of the Western Ghats in South India. Nilgiri Hills, which literally means the blue mountains, got their name from the purplish blue flowers of Neelakurinji that blossoms only once in 12 years. Each stamen is 2.15 ± 0.1 cm in length, and the anther length is 2.22 ± 0.25 mm. Strobilanthes kunthiana Small bluish violet campanulate flower with one side of the corolla slightly swollen from the base; set in dense broad bracted spikes. The difference in percentage fruit set and seed number per fruit between open-pollinated, self-pollinated, and cross-pollinated flowers was not significant (Kruskal–Wallis ANOVA). MANJU V. SHARMA, GIBY KURIAKOSE, KUNDARANAHALLI R. SHIVANNA, Reproductive strategies of Strobilanthes kunthianus, an endemic, semelparous species in southern Western Ghats, India, Botanical Journal of the Linnean Society, Volume 157, Issue 1, May 2008, Pages 155–163, https://doi.org/10.1111/j.1095-8339.2008.00786.x. In addition to her role as a wiseGEEK editor, Niki enjoys educating herself about interesting During the peak of flowering, two to four flowers open on each day in each inflorescence. Apis cerana indica foraging the pollen. All species are native to Asia, with most growing in tropical regions. In the wild, its purple flowers bloom only once every 12 years, an event celebrated in the Kandali Festival in the Pithoragarh district of India. After 30–60 min, the stigma returns to the original position to expose the receptive surface ready to receive pollen from the next bee visit. Perennials like bamboo flowers only once at the end of its life span i.e. One of the pollen baskets is also visible. The stigmas of flowers exposed to a single bee visit were examined for pollen load under a stereomicroscope; 75% of the flowers with an average pollen load of 8.45 ± 6.1 pollen grains were deposited by a single bee visit (N = 20). This keeps the pollen fresh until insect visitation and prevents pollen wastage. Strobilanthes dyerianus, commonly called Persian shield, is native to Burma (Myanmar). A mountain range of the area is named Nilgiri, meaning "blue mountains," in reference to the flowers. List of various diseases cured by Strobilanthes Crispus. Fig. Visitation rates per flower per hour on the same set of tagged flowers over the first and second days of opening (mean ± standard deviation). Strobilanthes ciliata is non-semelparous and the stigma is not sensitive to touch (M. V. Sharma, G. … The flowers are hermaphrodite and are borne on compactly arranged racemes (Fig. During the festival, women ritually destroy the plants, where the invading soldiers hid according to legend. Recently, the experts have warned that the iconic flora native to the Nilgiris, including more than 30 species of Strobilanthes, could be under threat of being displaced with the continuing advance of invasive flora such as Cestrum aurantiacum and Lantana camara.. About Strobilanthes Kunthiana. Strobilanthes kunthianus (Acanthaceae) is a semelparous species with synchronized flowering and mast seeding once in 12 years. Solution ( -(2) ) correct 1) Strobilanthes kunthiana (Neelakurani) flowers once in 12 yeass 2) Flowees of this plant Converted hilly tracks of kerala, Karnataka to Tamilnadu into blue. Neelakurinji (Strobilanthes kunthiana) is a shrub that grows abundantly in the Shola grasslands of the Western Ghats in South India above 1800 meters. It is perhaps the best-known species of Strobilanthes and its semelparous life event is well recorded with mass flowering incidents documented every 12 years since 1838 (Robinson 1935 ; Matthew 1971 ). This spectacle takes place only once in 12 years. Strobilanthes kunthiana Small bluish violet campanulate flower with one side of the corolla slightly swollen from the base; set in dense broad bracted spikes. Plants that bloom at long intervals like Strobilanthes kunthiana are known as plietesials, the term plietesial has been used in reference to perennial monocarpic plants "of the kind most often met with in the Strobilanthinae" (a subtribe of Acanthaceae containing Strobilanthes and allied genera) that usually grow gregariously, flower simultaneously following a long interval, set seed, and die. Flowers opened between 06.00 and 09.00 h. They remained fresh on the second day and senesced on the third day. The stigmatic lobes close together in response to touch by the pollinator. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. The flowers are used in Ayurveda Medicines .This Particular species is Conserved and propagated in Eco Herbs Sugandhavanam Nursery . We thank Mr Sajan Varma, Cochin, for Figure 1. The Gibraltar Campion classifies as a woody-based perennial plant. Jul 29, 2018 - Munnar is home to the highest concentration of neelakurinji plants in the country ∗ The reproductive period varies from organism to organism. During exiting, the body of the pollen-loaded bee does not come into contact with the stigma. The anthers can be induced to dehisce by a gentle touch with a needle. This pollen load was considered to be adequate for full seed set as it was twice the number of ovules present in the ovary. Reason Perennial plants have very short life span. View Answer. and unusual topics in order to get ideas for her own articles.

It is grown for its dark green foliage with bright, metallic-purple stripes radiating outward from the central leaf vein. Matthew (1971) also reported a 12-year flowering cycle for this species in the Palni Hills. Semelparous species invest all their resources into seeds and generally produce a larger seed crop (referred to as mast seeding) in comparison with most iteroparous species (flowering and fruiting at multiple times during their life span), which retain a major part of their reserves for continued growth. Semelpary is found in a wide range of plant species covering at least 20 families (Young & Augspurger, 1991). That happens about once every 12 years because the plant synchronizes its reproductive phase as a survival mechanism, flooding the area with new plants in order to outnumber predators, such as wildebeests. It is joined by seasonal rivulets and a few perennial streams originating from sholas in the upper reaches. Arrows indicate the path of bee entry and exit; arrowheads point to the receptive surface of the stigma. The amount of nectar decreased gradually on the second day and, by 18.00 h, it was only about 1.5 μL. Bee activity coincided with flower opening and reached its peak between 10.00 and 13.00 h (Fig. 1), covering the hills with a bluish purple carpet from its dense massive bloom, and attracting a large number of tourists. Strobilanthes kunthiana Small bluish violet campanulate flower with one side of the corolla slightly swollen from the base; set in dense broad bracted spikes. Obviously, therefore, a major reproductive strategy of a semelparous species is to evolve devices to facilitate reproductive assurance. It grows 3-4’ tall in frost-free climates, but typically grows 1-3’ in the St. Louis area. It also ensures that most of the available pollen comes into contact with the ventral surface of the pollinator during foraging. 2). Meera Bhardwaj The Republic of Ballari does it again as indiscriminate mining contaminates groundwater sources in Sandur. Shola-grassland mosaic in danger In Pambar merges with the Chinnar river at Koottar. The species achieves 100% pollination efficiency during the peak of flowering. The amount of nectar increased up to 4 μL by the morning of the next day in bagged flowers, indicating continued secretion of nectar during the night. As our preliminary studies showed that Apis cerana indica was the only frequent visitor to the flowers, the frequency of visits, foraging behaviour (for pollen/nectar), and foraging time were recorded for A. cerana indica. Recently, the experts have warned that the iconic flora native to the Nilgiris, ... Lantana camara is a small perennial shrub, which forms extensive, dense and impenetrable thickets. The stigma touched by a needle to induce the backward curvature of the stigma away from the path of the pollinator. The aim was to identify the features of the floral traits, pollination biology, and breeding system that are critical for reproductive success. Apart from preventing intrafloral selfing, the sensitive stigma effectively removes interference between pollen receipt and pollen export. Two other species of Strobilanthes, S. sessilis and S. ciliata, also flowered together with S. kunthianus in 2006, and we were able to collect limited data on the floral traits of these species. The immobilized insects were observed under a stereomicroscope to check for pollen load on their bodies. The leaves are also used as thatching for huts. About Strobilanthes Kunthiana. Flowering was initiated at the end of the second week of August 2006 and reached its peak in the second and third weeks of September Flowering declined towards the end of September and ceased by the end of October. Increased and rampant iron ore mining in the Swamimalai hills of Sandur in Karnataka has wrought upon serious ecological consequences. Reports of the movement of the stamen when touched by the pollinator to bring the anthers into contact with the body of the insect (Faegri & van der Pijl, 1979; Meeuse, 1996) are not comparable with the situation in Strobilanthes. Of these, the halictid bee carried a pollen load on its ventral surface and legs. Although two to three seeds developed in each fruit, some of them remained small and shrivelled in mature fruits. It is well established that the floral traits of species influence most aspects of reproduction (Ashman & Majetic, 2006). However, reports of a lack of fruit set in isolated clumps of several species indicate the prevalence of self-incompatibility.

Neelakurinji, scientifically known as Strobilanthes kunthiana, is a species of shrubs out of a total of 250 species of the genus Strobilanthes, out of which 46 of them are found only in the Shola forests of the Western Ghats of South India - across the states of Kerala, Tamil Nadu and Karnataka. An inflorescence at the peak of flowering. Stems sulcate, glabrous. = 5, N = 35), P = 0.0008]. Plietesials are plants that grow for a number of years, flower gregariously (synchronously), set seed and then die. The leaves of the plant are poisonous, but are used in folk medicine to treat inflammatory ailments and gastrointestinal disorders. There are many hypotheses, mostly with reference to bamboos, on the origin of semelpary: predator satiation, fire cycle hypothesis, increase in resource availability, and a mechanism for escaping parasites (Janzen, 1976; Keeley & Bond, 1999). The stigma is narrow, 1.91 ± 0.25 mm in length, and sharply curved. Visitation rates for Apis cerana indica (mean ± standard deviation). Semelparous species invest all their resources into seeds and generally produce a larger seed crop (referred to as mast seeding) in comparison with most iteroparous species (flowering and fruiting at multiple times during their life span), which retain a major part of their reserves for continued growth. 8). Our studies have highlighted several floral features of S. kunthianus that facilitate pollination efficiency. In general, protandry has been attributed to the avoidance of interference in pollen transmission (Bertin & Newman, 1993; Routley, Bertin & Husband, 2004). It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. ADVERTISEMENTS: Some of the differences between monocarpic plants and polycarpic plants are as follows: Monocarpic Plants: 1. Those type of plants are known as monocarpic or semelparous plants. It is perennial. The number of flowers visited during the day was calculated for both days. With the first rains of the year, the dried seed pods absorb moisture and pop audibly, dispersing their seeds to grow in the wet soil. An interesting feature of the flower of S. kunthianus is the dehiscence of anthers only in response to touch by a visiting insect. Mature fruits were harvested before dehiscence and the number of seeds was counted. View Answer. 5) and entered deep into the corolla tube to forage nectar. Knight TM, Steets JA, Vamosi JC, Mazer SJ, Burd M, Campbell DR, Dudash MR, Johnston MO, Mitchell RJ, Ashman T-L, Taylor PE, Card G, House J, Dickinson MH, Flagan RC, Oxford University Press is a department of the University of Oxford. This occurs due to its genetic structure, which may surprise some amateur researchers. Several hypotheses – improves the capture and germination of pollen, prevents intrafloral selfing, and reduces the interference with pollen dissemination – have been put forward to explain the adaptive significance of stigma closure (Webb & Lloyd, 1986; Fetscher & Kohn, 1999; Fetscher, 2002). Neelakurinji scientifically called as Strobilanthes Kunthiana is a flower in blue color Rajamala Wildlife Sanctuary in Munnar Kerala India Strobilanthes dyeriana (Persian shield) is a tropical plant grown for its dark green foliage with bright, metallic-purple stripes radiating outward. Neelakurinji, scientifically known as Strobilanthes kunthiana, is a species of shrubs out of a total of 250 species of the genus Strobilanthes, out of which 46 of them are found only in the Shola forests of the Western Ghats of South India - across the states of Kerala, Tamil Nadu and Karnataka. Nilgiri Hills, which literally means the blue mountains, got their name from the purplish blue flowers of Neelakurinji that blossoms only once in 12 years. Fig. To test the prevalence of apomixis, emasculated flowers (N = 50) were bagged and scored for fruit set. The flowering of Neelakurinji (Strobilanthes kunthiana), once in 12 years, is another attraction of Munnar hills. The stems of the beautiful perennial, meanwhile, most commonly appear as either light green or pinkish in color. 3. The insect visitation frequency varied significantly throughout the day [Kruskal–Wallis test: H = 21.1 (d.f. Self-compatibility seems to have adaptive significance in mast seeding of this species. It grows 3-4’ tall in frost-free climates, but typically grows 1-3’ in the St. Louis area. ADVERTISEMENTS: 2. After removing the debris, the number of pollen grains was carefully counted under a compound microscope. Examples: Rice, Wheat, Radish, Carrot, Bamboo, […] 4. The next generation of the plants are established from these seeds and the cycle is repeated. In perennial plant species, it is difficult to define vegetative, reproductive and senescent phases. Yet, the flower holds this status despite the fact that the marvelous species strongly resembles a small flower. Robinson (1935) recorded a 12-year flowering cycle for this species from the Nilgiri Hills between 1838 and 1934, based on the records of one of the earliest European families to settle in the Hills. = 11, N = 240), P = 0.0001]. The pistil is long (2.24 ± 0.13 cm) and the basal part of the ovary is covered with a conspicuous, yellow nectary. The flowering of Strobilanthes marks the death of the mother plant. The difference in the total number of visits on days 1 and 2 was tested using the Mann–Whitney U-test. A perennial herb or subshrub with numerous erect quadrangular stems.Blossoms gregariously once in 12 years. Leaves Strobilanthes kunthiana, or Neelakurinji, is native to South India. The stigma of this species is also sensitive to touch by pollinators, similar to S. kunthianus. Photo: Godwin Vasanth Bosco. Kurinji or Neelakurinji (Strobilanthes kunthiana), is a shrub that blossoms only once in 12 years. Mass flowering of Strobilanthes kunthianus during 2006 at Eravikulam National Park, Kerala, India. Flower buds were emasculated and bagged 1 day before anthesis. Strobilanthes is a genus of perennial flowering herbs and shrubs with about 250 species, at least 46 of which are native to India. Although the maximum number of visits occurred on the first day of flower opening (15.4 ± 4.7 visits per flower per hour), a considerable number of bee visits (3.2 ± 3.5 per flower per hour) were recorded on the second day as well. The Nilgiri ... Perennial streams sprung from the Sanctuary provide source of drinking water to the adjoining villages of Kadavary, Kottakombur, Kovilur and Vattavada. Bees foraged nectar exclusively on the second day. In bagged flowers, the anthers failed to dehisce by the evening of the first day, and even on the second day they showed a thin slit along the anther but pollen grains were not exposed from the anther until physical disturbance. Although most of the pollen is foraged in the morning hours on the first day, the flowers offer a considerable amount of nectar to the visitors, and the stigma remains receptive even on the second day. Fig. The curved, tubular violet flowers are produced over a long and valuable flowering season - usually until October or even later. pollution-free cool atmosphere, greeneries, trekking, watching wildlife, peaceful but low cost shelter and budget shopping for spices. at The festival also commemorates the defeat of Zorawar Singh's army in 1841, which took place when the Kandali were in bloom. The pollen to ovule ratio is 720 : 1. To study the floral phenology, flower buds (N = 30) that would open the next day were tagged and kept under observation to record anthesis, anther dehiscence, and other floral changes until they senesced. Strobilanthes sessilis is a semelparous species reported to flower once in seven years. It is a soft-stemmed, tropical, evergreen shrub or subshrub that is grown primarily for its attractive iridescent purple foliage. Flowers offer both pollen and nectar as reward. Fruit and seed set was very high, even under open-pollination conditions, and was comparable with that realized in controlled pollinations. II. It also remains relatively small in terms of physical size. In both experiments, Kruskal–Wallis ANOVA was used to analyse the difference in visitation rates across time slots during the lifetime of the flower. The frequency of flowering of successive generations in such species is highly variable. Details of fruit set and seed number in various pollination treatments are given in Table 1. Die, the flower holds this status despite the fact that the floral traits has mast. We thank Mr Sajan Varma, Cochin, for Figure 1 first brushes the receptive.
