The High Wavy Mountains are remarkable for their endemic flora, particularly orchids.
Among the 34 orchids reported by Blatter in 1928, some ofthem could not be located and
are considered as possibly extinct, mainly due to habitat degradation. This paper deals
with 64 species of orchids including all the species reported by Blatter, except
Chrysoglossum halberii Blatt., Odontochdus rotundifolius Blatt. relocated. Bulbophyllum
agastyamalayanum Gopalan & Henry is reduced to B. xylophyllum Par. & Reichb.f.
