Description: Hemiparasitic aerial stem-parasitic shrubs, glabrous or stellate-hairy; haustorial attachment single, without external runners.
Leaves opposite, often reduced or apparently absent, entire, without stipules.
Flowers actinomorphic, unisexual and plants monoecious [or dioecious], 2–4-merous, small. Inflorescences cymes or flowers developing successively in clusters. Perianth in 1 whorl; tepals 2–4, triangular, valvate. Stamens 2–4, opposite tepals; anthers fused to tepals or to each other or free, 1- to many-locular, opening by pores. Ovary inferior, without differentiated loculi or ovules, surmounted by a nipple-like stigma.
Fruit berry-like, with a single seed surrounded by a viscous layer; endosperm present.
Distribution and occurrence: World: 7 gen., 400 spp., chiefly trop. regions. Aust.: 4 gen., 14 spp., all States.
