Although Mr C R Fraser-Jenkins has explained the details about Cheilanthes (Aleuriopteris) bicolor, he has not given the reasons for the name change. In India this fern was known as Cheilanthes farinosa. It was Manton, Roy & Jarrett (1966) who pointed out that the name for the indian plants which were diploids need to be changed, since the name C farinosa was for the triploid from Yemen.Incindently there is a tetraploid also. Manton et al did not propose any new name for the diploid. After that a lot many people suggested various names for the Indian taxon. Mr Fraser-Jenkins desreves the credit for locating a specimen of Pteris bicolor (specimen in Brussels) collected by Roxburg (from Kumaun Himalaya) and this was the Hiolotype rather than C dealbata of Wallich. (Details given in 'AN Illustrated Fern Flora of the West Himalaya By S P Khullar, Vol 1. Published by MS International Book Distributors, Dehra Dun (1994). It was in this flora that the name Cheilanthes bicolor (Roxberg) Fraser-Jenkins was used following Fraser-Jenkins (1992). I feel when a name change is suggested reasons for the change of name should be given S P Khullar
