Trees or shrubs of usually terrestrial habitat, parasitic on roots of other vascular plants. Leaves dark green, paired, broadly lanceolate to ovate. Inflorescences a raceme of stalked triads, median flowers of triads sessile, lateral ones short-stalked, each subtended by a green, foliaceous bract/bracteole. Flowers bisexual, 6-or 7-merous; anthers versatile and dorsifixed. Fruit a rather large, pulpy berry; seed not viscid, with grooved, white endosperm and dicotylous, small embryo. (x = 12, 24).
Tall shrubs or small trees living upon earth, but parasitizing roots of other plants. Leaves opposite, more or less coriaceous, almost always minutely, but evidently, punctate beneath. Flowers conspicuous, colored, 4-8-merous, perfect, in ternations, these in racemes or corymbs; bractlets conspicuously developed, free, persistent; pedicels often unequal. Pollen grains 3-angled, the exine granulose. Ovary said to be 2-6-celled, but this scarcely convincing. Fruit baccate, the seeds albuminous.
