For full synonymy see Dans. Bull. Jard. bot. Buitenz. 11: 397 (1931).
Aerial stem-parasites; runners usually present; leaves alternate or scattered (less frequently opposite); venation pennate. Inflorescence a simple axillary raceme or spike (sometimes reduced to a simple 2-flowered umbel or to a single axillary flower); bracts single under each flower. Corolla in the mature bud usually inflated, curved; petals in the open flower 5, gamopetalous and forming a tube irregularly divided into lobes. Anthers basifixed, immobile, 4-locular; pollen trilobate. Basic Chromosome Number.-x = 9.
A genus of about 30 species distributed from tropical Africa to
Australia, with the largest centre of development in western Malesia.
Species limits are generally very difficult to determine (see
note under D. falcata). Of the four species which occur
in New Guinea and adjacent islands, three are rather localized
endemics and the other extends to India and northern Australia.
