The male flower has 3–8 stamens; the female has a platanaceae found in india and grows throughout the superior ovary with 3–7carpels. Plane trees are wind- valley.This paper addresses the distribution and phenology pollinated. Male flower-heads fall off after shedding their of the species in Kashmir. Present investigation revealed pollen. Flowers small, inconspicuous, hypogynous, regular unisexual, receptacle short, smooth, hypogynous disk that it grows in plains and hilly regions of Kashmir valley .The Selected sites were surveyed viz; (Srinagar, absent, perianth reduced, sepals number three to four, Baramulla, Budgam, Pulwama Ganderbal, Anantnag and rarely eight, free or basally fused, shorter than the petals, Shopian). During the present investigation the species triangular. Petals number three to four, rarely eight, was found sporadically distributed in Kashmir Himalaya truncated-spatulate or vestigial, scarious, frequently absent in the female flowers, male flowers with androecium across an altitude of 1500-3000 m asl. A total of 2052 individuals of Platanus orientalis were found from different haplostemonous, isostemonous, with number three to four, areas of Kashmir. The highest population density was rarely eight, stamens, gynostemium short or vestigial, recorded from Srinagar (580 individuals), followed by anthers basifixed, not versatile, dithecous, tetrasporangiate, Ganderbal (485), Budgam (404), Baramulla (298) and elongated, connectivum apically widened, peltate, Anantnag (285).The present study reveals that the lower dehiscence along longitudinal valves; pistillidium altitudes enters phenological phases earlier than upper sometimes present, female flowers with superior gynoecium carpels apocarpous in two or three whorls, altitudes. imperfectly closed apically, surrounded by large petals, linear stylodious, stigmas internal, decurrent in two ridges, Key words Platanus orentalis, morphology, altitude, more or less dry, two ovules per carpel but one nearly always distribution. aborts, orthotropous, bitegmic, crassinucellated, pendulous, apical to marginal placentation, three or four Platanus orientalis L., called ‘Bouin’ in Kashmiri staminodes 3-4, no nectarines. language is the only species of family Platanaceae found The tree has the capability of growing in the latitudes in India and grows throughout the valley. It is a woody of most temperate region however it is benefitted to a large perennial tree, native to the eastern Mediterranean regions, extent from warm summers. It is a huge tree having from where it spread to other parts of the world (Baily, considerable breadth and thick leaves which have the 1953). Its natural distribution extends from southern Balkans, tendency to orient in a horizontal position basically known Crete, the mountains of South Turkey, West Syria, North for the coolness and shade it offers to the people in the Iraq and Iran, eastwards to the Kashmir, where it is known times of hot season. The tree has been honored with the as the Chinar (Kavadas, 1956). The oldest Chinar tree in Garden Merit award of Royal Horticultural Society. Asia is found in Chittergam Chadura village in Budgam district of Central Kashmir, which has a girth of 31.85 m at The bark posseses antiscorbutic and antirheumatic ground level and 14.78 m at breast height. It is mentioned in properties.Boiled in vinegar its given in diarrhoea and historical books of Kashmir like “A dictionary of Kashmiri dysentery .Brulsed fresh leaves are applied in opthaimia.A proverbs and sayings” by James Hinton Knowles (1885), walk over fallen dry chinar leaves makes a rustling musical “ Valley of Kashmir” by Sir Walter Lawrence’s (1895) and sound until the dry leaves are gathered and burnt to make in “The Kashmir Gazetteer” (1889-1895).

When Akbar addition they are good source of certain important chemical took over the reins of Kashmir in 1586, he ordered the compounds like platanin, tannin, allantain, phlobaphene, planting of 750 chinar saplings on the shores of Dal Lake mannitol, platanolic acid and platanol,which can be near Hazratbal and Naseem Bagh. In the Valley it is extracted for novel use.(Mohmmad Imran Kozgar $ commonly used in landscape design , tolerance of pollution, Samiullah Khan) tolerance of difficult soil condition (Zencirkiran, 2010) and MATERIAL AND METHODS its deep shade and beautiful autumn colour. The important plant species namely ‘ Platanus A tree with widely spreading branches,maple like orentalis’ constitute the material for present study.

Male and female flowers are separate, conservation of the two species. The data on various but borne on the same plant (monoecious). The number of aspects were recorded along the following lines. 476 Trends in Biosciences 11 (4), 2018 Survey, collection and documentation An extensive exploration of different habitats of Kashmir was carried out to identify specific areas across different geological conditions covering a wide range of habitats. Present investigation revealed that grows in the plains and hilly regions of Kashmir valley and seven sites (Srinagar, Baramulla, Budgam, Pulwama Ganderbal, Anantnag and Shopian) were selected for the further studies. The selected sites were surveyed. Herbarium specimens were prepared following standard herbarium procedures The populations were analyzed for morphological traits Population density of Plants (30x30 sq m), Mean circumference (m), Leaf Area (cm2), Petiole size (cm), Fresh Weight of Leaves(g). Dry Weight of Leaves (g) and Weight of Ten Seeds (g). Both qualitative and quantitative parameters were studied on the basis of morphological features given by Nath (1996). Fifteen plants were selected and tagged from each population for morphological and phenotypic variability by following proper procedure.
