Phalaenopsis zhanhuoensis (Orchidaceae, Vandeae), a new species from Yunnan, China

Abstract

A new species of Orchidaceae, Phalaenopsis zhanhuoensis, from Xichou County, Yunnan, China, is described and illustrated. The novelty is close to P. taenialis, P. wilsonii, and P. stobartiana, but differs from them by having a distinct, fleshy anterior callus with a deeply lobed apex at the base of the labellum and lateral lobes of labellum reflexed and facing outward.
