Herbs, epiphytic, small to medium-sized. Rhizome short or elongate, stout, internodes short or to ca. 4 cm, with pubescent roots.
Stems pseudobulbous, pseudobulbs of 1 internode, short to ca. 13 cm, sometimes with several ferruginous reddish brown pubescent
sheaths, distinctly or slightly swollen at base, then tapering distally, upper portion cylindric, with 1–4 leaves at apex. Leaves erect or
spreading, conduplicate or terete, ± linear-oblong or ligulate, leathery, articulate at base to a short, sometimes pubescent leaf base or
to stem. Inflorescences 1- to few flowered, up to 3 per pseudobulb, emerging from an acute sheath, often densely ferruginous reddish
brown pubescent; floral bracts often ferruginous pubescent. Flowers not resupinate or resupinate, opening widely, densely pubescent.
Sepals and pedicel and ovary densely pubescent. Dorsal sepal free; lateral sepals connate with column foot forming a distinct shortly
conic mentum. Petals free, smaller than sepals, glabrous; lip entire or 3-lobed in apical half; lateral lobes (when present) erect; midlobe
with thickened margin; callus of 2 longitudinal central and 1 apical, somewhat verrucose ridges. Column short, somewhat
clavate, sometimes pubescent, foot ca. as long as or longer than column proper, incurved; pollinia 8, compressed ovoid or clavate.
About five species: widespread in Indonesia, Laos, Malaysia, New Guinea, Thailand, and Vietnam, extending east to S China (Hainan); one
species in China.
