Notes on Aphyllorchis gollanii and Aphyllorchis alpina (Orchidaceae) and lectotypification of both names
Morphological characters of Aphyllorchis gollanii Duthie have been studied and compared to those of Aphyllorchis alpina King & Pantling based on protologues, type specimens of both species and other specimens and fresh collections from Indian Himalayan Region. Both species proved to present identical or overlapping characters. Therefore, they are treated as conspecific. Lectotypes are designated […]
