India has been identified as one of the 12 megadiversity countries (Myers, 1992) with about 126,000 species. India has 8% of the global biodiversity, even though it covers only 2.4% of the land area of the world (Khoshoo, 1995). The Eastern Himalayas and Western Ghats are also among the 18 biodiversity hotspots in the world (Khoshoo, 1995). The Western Ghats covers only 5% of the land area of India, but has 30% of India’s species. It has about 5,000 flowering plant species of which 1,500 are endemic (Nair, 1991). There are 58 endemic plant genera, of which 42 are monotypic. About 490 species of trees occur of which 308 (62.5%) species in 58 families are endemic. About 267 species of orchids occur belonging to 72 genera, of which 130 species are endemic.
