Aerial stem-parasitic shrubs, often robust, with epicortical runners bearing secondary haustoria. Leaves mostly opposite. Inflorescencess axillary or inserted on the epicortical runners, a simple raceme or spike of decussate pairs of flowers, sometimes few-flowered and seemingly umbellate; bracts 3 under each flower, free or variously connate. Corolla 6-merous, gamopetalous, in mature bud with 6 keels or wings at the point of reflexion of the lobes, usually weakly zygomorphic but sometimes regular. Anthers basifixed, immobile. Style simple, usually with a knob-like stigma. Fruit ellipsoid to nearly globose. Fig. 35. Fig. 36. Fig. 37. Fig. 38. Fig. 39.
