Habit
Trees, shrubs or subshrubs, dioecious or androdioecious
Indumentum
Young plants practically always with stellate indumentum, particularly on inflorescences, sometimes simple hairs present as well
Leaves
Leaves alternate, imparipinnate, 3-foliolate or rarely simple, usually clustered at the end of branchlets; leaflets opposite or subopposite, entire or toothed
Inflorescences
Inflorescences sometimes produced before the leaves, paniculate or spike-like
Flowers
Flowers 4-merous, with a cup-shaped crenulate disk; male flowers with 8 stamens and a rudimentary pistil; female or bisexual flowers with stamens shorter than ovary, ovary ovoid, 4-celled and with 4 subterminal styles
Fruits
Drupes ovoid to ± oblong, with prominent style-bases; endocarp woody, 1–2-celled by abortion and with 1–2 opercules at the apex
Seeds
Seeds somewhat reniform, compressed.
Distribution
Some 40 species in tropical Africa and Socotra, with three species extending into tropical Arabia and one species in southern Asia eastwards to China.

Anacardiaceae, J. O. Kokwaro (University of Nairobi). Flora of Tropical East Africa. 1986

Habit
Trees, shrubs or suffrutices; young plants usually with stellate indumentum; bark tough and used as string
Leaves
Leaves alternate, imparipinnate, trifoliolate or rarely unifoliolate, usually clustered at the end of the branches; leaflets sessile or petiolulate, opposite or subopposite, usually entire
Inflorescences
Inflorescences often produced before the leaves, ♂ essentially paniculate but the branchlets reduced to mere knobs on which the flowers are clustered so that they seem spike-like, ♀ racemose to spicate; sometimes the spikelike panicles are themselves branched
Flowers
Plants dioecious, sometimes the trees being entirely ♂ and others producing apparently bisexual flowers in which the stamens may or may not be functional Male flowers: calyx 4-partite, segments imbricate; petals 4, imbricate; stamens 8, with the subulate filaments inserted below the disk; anthers dorsifixed; disk somewhat cup-shaped, 8-crenulate with a 4-cleft vestigial ovary at the centre Female flowers: hermaphrodite or perhaps functionally ♀ only; perianth as in ♂; stamens shorter than ovary, but normally antheriferous; ovary ovoid or subglobose, 4-locular, with 2–3 abortive locules; ovule pendent from a long funicle attached at the apex of the locule; styles 3–4, free, subterminal; stigmas simple or subcapitate
Male
Male flowers: calyx 4-partite, segments imbricate; petals 4, imbricate; stamens 8, with the subulate filaments inserted below the disk; anthers dorsifixed; disk somewhat cup-shaped, 8-crenulate with a 4-cleft vestigial ovary at the centre
Female
Female flowers: hermaphrodite or perhaps functionally ♀ only; perianth as in ♂; stamens shorter than ovary, but normally antheriferous; ovary ovoid or subglobose, 4-locular, with 2–3 abortive locules; ovule pendent from a long funicle attached at the apex of the locule; styles 3–4, free, subterminal; stigmas simple or subcapitate
Fruits
Drupe compressed, obovoid, ovoid or ± oblong, showing persistent separated style-bases; mesocarp thin; endocarp woody, surface ridged and alveolate, with 1–2 ovate opercules at the apex
Seeds
Seeds somewhat reniform, compressed; cotyledons plano-convex.

Anacardiaceae, Rosette Fernandes & A. Fernandes. Flora Zambesiaca 2:2. 1966

Habit
Shrublets, suffrutices, shrubs or trees, with the young parts and inflorescences stellately tomentose.
Leaves
Leaves alternate, imparipinnate or 3-foliolate or rarely 1-foliolate, usually clustered at the end of the branches; leaflets entire, sessile or petiolulate.
Inflorescences
Panicles terminal or axillary, ± branched and pyramidal or spike-like (the lateral branches very short), often arising before the leaves.
Flowers
Male flowers: calyx 4-partite, the segments imbricate; petals 4, imbricate; stamens 8 with the filaments subulate inserted below the disk; anthers ovate or sagittate, dorsifixed; disk ± cup-shaped, 8-crenulate with a 4-cleft vestigial ovary at the centre. Female flowers: perianth similar to that of the male flowers; staminodes short; ovary ovoid or subglobose, 4-locular, with 2–3 abortive loculi; ovule pendent from a long funicle attached at the apex of the loculus; styles 3–4, subterminal; stigmas ± capitate.
Fruits
Drupe obovoid or ovoid, ± compressed or subglobose; mesocarp thin; endocarp woody, the surface unequally ridged and alveolate, with 1–2 ovate opercules at the apex.
Seeds
Seeds ± reniform, compressed; cotyledons plano-convex.
