It is distinguished from the others of section Sestochilos (Breda) Benth. & Hook. f. by its inflorescence with 2~5 flowers, sepals and petals with ciliate fringe of silky hairs at edges. Dendrobium menglaense X. H. Jin & H. Li is reduced to D. chrysocrepis Parish & Rchb. f. ex Hook. f. as a synonym, and characterized by solitary flowers with spoon-like lip which are borne on the flattened stem. Images and descriptions of the two species are provided.
