Genus Ascoglossum

Ascoglossum Schltr.,
Repert. Spec. Nov. Regni Veg. Beih. 1 (1913) 974

Monopodial epiphytic plants. Stem elongated. Leaves many, sheathing at the base, glabrous, dorso-ventrally flattened, articulate, duplicate, leathery. Inflorescence lateral, a panicle. Flowers small, resupinate, vivid magenta. Sepals free. Petals free, similar to the dorsal sepal. Lip adnate to the column, spurred, not mobile. Column-foot absent. Pollinia 4, arranged into two masses, solid-waxy, caudicles absent, stipe present, viscidium present.

Philippines, Moluccas, New Guinea, Solomon Islands. One, non endemic, species [Ascoglossum calopterum (Rchb.f.) Schltr.].

Epiphytes in lowland forest.

Undoubtedly a close relative of Renanthera, from which it mainly differs in the colour of the flowers and the reflexed sepals and petals. Not as yet common in cultivation, although it certainly has more horticultural potential than most New Guinea monopodial orchids.
