Cymbidium Weishanense (Orchidaceae; Epidendroideae), A New Species From China: Evidence From Morphological And Molecular Data

A new species of Cymbidium (Orchidaceae), C. weishanense, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. weishanense is similar to C. concinnum but differs in several floral characteristics. Molecular analyses based on nuclear ribosomal (ITS) and plastid DNA (matK and rbcL) support the status of C. weishanense as a new species. Due to the low support for nrITS, it is possible that this is a natural hybrid of C. concinnum with C. insigne or another related species.
