Peristylus Blume

There are 8 species recorded from Sri Lanka including two endemics. Among these one of the most common species observed was, P. spiralis (Syn: Habenaria torta Hook. f. ) and this is a VU species ( MOE, 2012). In 1981, Jayaweera has recorded that this species is discovered above 1220 m elevation in open slopes of the montane temperate forests although Fernando & Ormerod (2008), stated that this species is dispersed in submontane zone. Contrary to Fernando & Ormerod (2008), observations were made in Horton Plains at elevation of 2110 m in the montane zone.
