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

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.
