Dorsal sepal free, erect or spreading, longer than the triangular-ovate: 
acuminate lateral ones, which are either falcate or reflexed about the 
middle, base of laterals adnate to the foot of the column. Petals smaller 
and narrower than the sepals. Lip articulated to the foot of the 
column, mobile, inflexed at the base, recurved above, entire or 
denticulate at the base, rarely somewhat 3-lobed. Column short, 
broadly dilated and winged on both sides, terminating above in 
square or rounded teeth; base produced into a short foot. Anther as 
îm Bulbophyllum.—Epiphytic herbs, with stout creeping rhizomes ; 
pseudobulbs sessile in the axil of a sheath, mostly 3—-5-angled, 2- or 1- 
leaved. Scapes arising from the base of the pseudobulbs, simple ; apex 
dilated into a flattened, often ensiform and almost foliaceous SE 
along either side of which the flowers and bracts are distichously 
arranged. Bracts usually ovate or triangular, ultimately much 
deflexed. Flowers small, pedicelled, curved.

South Africa and one reported from Madagascar, of which the habitat requires 
confirmation.
