Habit and leaf form. Trees (small), or shrubs, or lianas. Partially parasitic. On roots of the host. Leaves cauline. Stem internodes solid. Self supporting, or climbing. Mesophytic. Leaves alternate; distichous; petiolate; non-sheathing; simple. Leaf blades entire; elliptic to ovate, or oblong to ovate; pinnately veined (usually prominent though fine, midrib prominent beneath, lateral veins conspicuous); cross-venulate; attenuate at the base (often), or rounded at the base (sometimes). Leaves without stipules. Leaf blade margins entire. Leaf anatomy. Extra-floral nectaries absent. Stem anatomy. Secondary thickening developing from a conventional cambial ring.
Reproductive type, pollination. Fertile flowers hermaphrodite. Unisexual flowers absent. Plants hermaphrodite.
Inflorescence and flower features. Flowers aggregated in ‘inflorescences’; in racemes (or raceme-like). Inflorescences axillary. Flowers pedicellate (pedicels and rachis tomentose with brown or yellow hairs); bracteate (each subtends 3 flowers, scale-like or peltate or broadly ovate, ciliate, closely imbricate, caducous before anthesis). Bracts deciduous. Flowers ebracteolate; small; fragrant; regular; 4 merous, or 5 merous; cyclic; tetracyclic. Free hypanthium absent. Hypogynous disk present; of separate members (alternating with the stamens). Perianth with distinct calyx and corolla; (4–)5; 2 -whorled; isomerous. Calyx present (B); (4–)5; 1 -whorled; polysepalous, or gamosepalous; lobulate, or blunt-lobed; open in bud; cupuliform; regular; persistent; non-accrescent. Calyx lobes oblong. Corolla present (B); (4–)5; 1 -whorled; polypetalous, or gamopetalous; valvate; regular; green (yellowish). Androecial members definite in number. Androecium 4–5. Androecial members free of the perianth, or adnate; all equal; free of one another; 1 -whorled. Androecium exclusively of fertile stamens. Stamens (4–)5; all more or less similar in shape; isomerous with the perianth; alternisepalous. Anthers dehiscing via longitudinal slits; tetrasporangiate. Gynoecium 2–5 carpelled. The pistil 1 celled. Carpels reduced in number relative to the perianth to isomerous with the perianth. Gynoecium syncarpous; eu-syncarpous; superior. Ovary unilocular; 1 locular; sessile. Gynoecium non-stylate (AK), or stylate (B). Styles 1; attenuate from the ovary; apical; shorter than the ovary at anthesis. Stigmas 1. Placentation basal, or free central. Ovules in the single cavity 1; pendulous, or ascending; non-arillate; anatropous.
Fruit and seed features. Fruit puberulous, orange-yellow, edible; endocarp thin and crustaceous, yellow; indehiscent; a drupe; 1 locular; 1 seeded. Seeds endospermic. Endosperm oily. Seeds without a testa. Embryo well differentiated. Cotyledons (2–)3, or 4. Testa lacking.
