“…Although, the Indian squill: D. indica has been investigated for various parameters [3], [4], [5], [16], [20], [28], [29], [30], [31], [32], [33], [36], [39] howerver the AM fungal status in it has been found quite ignored with very few exceptions. Earlier studies of Parameswaran and Augustine [22], suggested AM fungal distribution and ecology of Urginea indica in scrub jungle from Tamil Nadu and also in few populations by Shiva Kameshwari [17] in non-coastal sand dune regions.…”

“…The genus Drimia (Syn. Urginea) has been extensively studied for biosystematics [16], [32], [33]; cytological [3], [28], [29], [30], [36], [39]; cytotaxonomical-genetical aspects [4], [31] and very recently for DNA bar-coding as well as for molecular markers (ITS and matK) [5], [20]. Ethno-medicinally bulbs of D. indica has proved antiulcerous, antinematodal, antitumorous, anthelmintic antiarthrities properties and also used to cure skin diseases like warts, abscesses, boils, cardiac diseases, antidote to scorpion sting [18].…”

Abstract:In the present study on Urginea indica, twelve different populations from southern part of India is considered. Fifteen parameters have been scored for each population to understand the relationship between different races. The main objective is to trace phylogeny in populations of U. indica to construct phylogenetic tree. The phylogenetic tree obtained is an unrooted tree. The parsimony tree describes that Shimoga and Chamundi hill populations have parallely evolved and forms the out group. Dopaegowdanapura population has given rise to Gopalaswamy betta, Gopalaswamy betta has given rise to Banganavadi and Banganavadi has given rise to one population which is missing in the tree and the missing population has given rise to Gorur on one hand and to Krishna Raja Sagar island and Gandhi Krishi Vighnayana Kendra on the other hand. Krishna Raja Sagar island and Gandhi Krishi Vighnayana Kendra shares a common clade. Gorur has given rise to Papanasini and Papanasini has given rise to Channamallipura, from Channamallipura another population has been evolved which is missing and the missing population has given rise to Basavanahalli and Ranganthittu which shares a Common clade. The Parsimony tree shows that these populations have evolved parallel. Dopaegowdanapura is the oldest from which all others are evolved. Ranganathittu and Basavanahalli form the youngest and latest. Therefore it is an unrooted tree with distance. Each population varied in their morphology and chromosome number and called as cytotypes. Difference in morphological character is mainly because of genetic characters. Habitat does not seem to play major role to mould morphological features.

“…Sci. 2 (2): 280-289 (2010) Locality measurements of various morphological features followed the methods of Dixit and Yadav (1989). The attributes measured on each populations for their vegetative characters were height of the plant, length of root, circumference of the bulb, no of leaves / plant, leaf index from July to November and reproductive characters were length of inflorescence, length of pedicel, number of flowers / plants, length of flower, stamen, gynoecium and fruit length which starts from April to June.…”

An attempt has been made to enquire into the morphological variations which leads to evolutionary divergence of populations of Urginea indica Kunth. In particular, there were considerable morphological variations within the species. The thirty two cytotypes showed distinct morphological differences in shape, size and colour of bulb and leaf, the length of inflorescence and flower colour. The morphological complexity is accompanied by high degree of cytological variations. Preliminary measurements of reproductive, characters have shown that no noteworthy results may be obtained in this characters except pedicel length but the vegetative character deviated significantly. Flowering and blooming time varied that also played a role in isolation of these populations. These morphological differences have a genetic basis and would be worthy in recognizing them as a separate sub specific taxon.
