Dendrobium naungmungense (Orchidaceae, Dendrobieae), a new species from Kachin State, Myanmar

Abstract

<i>Dendrobium naungmungense</i>, a new species from Naungmung, Kachin State, North Myanmar, is described and illustrated. It is morphologically similar to <i>D. ciliatilabellum</i> and <i>D. vexabile</i>, but the epichile is oblong with three long-ciliate laminae and the column wing has significant denticulation. A preliminary risk-of-extinction assessment shows that the new species should be regarded as Critically Endangered (CR) according to the IUCN Red List Categories and Criteria.
