Bulbophyllum yongtaiense (Orchidaceae, Epidendroideae, Dendrobiinae), a new species from Fujian, China: Evidence from morphological and molecular analyses

Abstract

Bulbophyllum yongtaiense, a new orchid species from Fujian, China, is described and illustrated based on morphological and molecular analyses. Detailed morphological comparisons indicate that B. yongtaiense is similar to B. kuanwuense, but it can be distinguished from longer scape, fimbriate-ciliate on margins of dorsal sepals and petals, petals with obtuse apex and a lip with finely papillose near base. Molecular analyses based on nuclear ITS and plastid matK, atpI-atpH, and trnL-F DNA sequence data support B. yongtaiense is genetically similar to B. hirundinis and B. pecten-veneris, but it can be distinguished from them by having shorter lateral sepals, petals with obtuse apex and a lip with finely papillose near base.
