Bulbophyllum tseanum (Orchidaceae) a new record for the flora of Viet Nam
Main Article Content
Abstract
Bulbophyllum tseanum found in Quang Nam Province is recorded as new for the orchid flora of Viet Nam. Previously this species was only recorded in Hong Kong and Hainan (South-East China). Living specimens were collected from Quang Nam province and flowered successfully in a private garden in Da Lat city, Lam Dong province. Based on morphological characters, B. tseanum is very close to B. lepidum in plant habit, shape and color scheme of flowers, but can be distinguished by its broadly ovate dorsal sepal, longer lateral sepals, narrow petals with shortly caudate apex, size of stelidia and column wing shape. The description of Vietnamese plants is presented, accompanied with the analytical plate and taxonomic notes.
