Cylindrolobus gaoligongensis sp. nov. (Orchidaceae, Podochileae) from Yunnan, China, and improved description of C. arunachalensis

Abstract

A new species of Cylindrolobus (Orchidaceae), C. gaoligongensis from the Gaoligong Mountain, northwestern Yunnan, China, is described and illustrated. It is morphologically similar to C. arunachalensis and C. gloensis , but can be distinguished from them by having orange to pink and triangular‐ovate lip mid‐lobe with mucronate apex, front margin of lateral lobes yellow to white and with short glandular hairs gradually transitioning to dense long hairs, two central calli connected to a keel toward mid‐lobe in the disk, and three rows of white long hairs at the base of the disk. Additionally, an improved description and illustration of the closely related species C. arunachalensis , is also provided.
