Dendrobium ser. Formosa Bentham & J. D. Hooker, Gen. Pl. 3: 500. 1883 ["Formosae"].

Roots smooth. Stems linear, mostly tall, stout, usually evergreen, new sheaths (and sometimes leaves) black- or brown hirsute, hairs deciduous when old. Flowers large, usually white, rarely yellow or with a contrasting lip. Mentum prominent, usually straight, conic, elements fused distally into a spur, nectar present in some species. Lip 3-lobed, crest usually finely hairy, often with multiple low keels, blade glabrous.

About 51 species: Himalayas to Indonesia and Philippines; eight species (one endemic) in China.

Reviewer L. Averyanov notes that Dendrobium chapaense Averyanov (Rheedea 16: 3. 2006), described from N Vietnam, also occurs in China. However, the present authors could not substantiate this record because they found no relevant specimens.
