Mischobulbum Schltr.,
Repert. Spec. Nov. Regni Veg. Beih. 1 (1911) 98
Sympodial terrestrial plants with short rhizomes. Pseudobulbs consisting of one internode, one-leaved. Leaves not sheathing at the base, glabrous, plicate, not deciduous, convolute, without petiole, cordate, often mottled, thin-textured. Inflorescence arising from a specialized leafless shoot (heteranthous), a 2- to several-flowered raceme. Flowers medium-sized, resupinate, usually greenish, brownish or yellowish with a paler lip. Sepals free. Petals free, rather similar to the dorsal sepal. Lip without spur, not mobile, with two or three distinct, often wavy crests. Column-foot long. Pollinia 8, solid, caudicles present, stipe absent, viscidium absent.
Distribution
Northeast India, China, South-east Asia, Malaysia, Indonesia, the Philippines, Papua New Guinea. Eight species; in New Guinea one species [Mischobulbum papuanum (J.J.Sm.) Schltr.].
Habitat
Terrestrial in lowland and montane forest.
Notes
Mischobulbum is a near relative of Tainia. It differs in the cordate leaves that lack a petiole. These rather attractive plants are uncommon in nature and still more so in cultivation.
