Abstract

A new species, Dendrobium bannaense, is described from Yunnan, China, based on the molecular and morphological evidence. It belongs to section Dendrobium according to analysis of combined nrITS and plastid datasets (matK, rbcL, trnH-psbA, and trnL intron). Morphological analysis reveals that D. bannaense is similar to D. parishii, but differs in having a white lip with purplish stripes and without a deep purple blotch on either side; the disk is with 3 longitudinal ridges, extending from base to upper-middle part, and lower-middle part is thickened and swell as callus shape at the joint of lip and claw.
