Parasitic green shrubs or herbs, containing chlorophyll, growing on 

 woody plants and absorbing food from their sap through specialized 

 roots called haustoria (a few tropical species terrestrial). Leaves in the 

 following genera opposite, in Bazoumofskya reduced to opposite scales. 

 Flowers regular, terminal or axillary, dioecious or monoecious, and peri- 

 anth simple, or in some genera perfect, and with perianth of both calyx 

 and corolla. Calyx-tube adnate to the ovary. Stamens 2-6. Ovary soli- 

 tary, erect; style simple or none; stigma terminal, undivided, obtuse. 

 Fruit a berry. Seed solitary, its testa indistinguishable from the endo- 

 sperm, which is usually copious and fleshy; ernbryo terete or angled. 

 About 21 genera and 500 species, widely distributed; most abundant in 

 tropical regions. 



Perianth of two series of parts ; flowers mostly perfect. 1. Dendropemon.
