Aerial stem-parasitic shrubs with epicortical runners bearing secondary haustoria. Leaves opposite; venation pinnate. Inflorescences axillary, a raceme of decussate pairs of pedunculate dichasia (triads); bracts single under each flower. Corolla 6-merous, regular, gamopetalous to above the middle. Anther immobile, introrse, with an extension from the base which is free from the filament so that the filament appears dorsifixed. Style simple, articulate at the base, with a knob-like stigma. Fruit ellipsoid. Fig. 34.
