Euphorbiaceae, A. Radcliffe-Smith. Flora Zambesiaca 9:4. 1996
- Morphology General Habit
- Dioecious trees or shrubs.
- Morphology General Indumentum
- Indumentum simple and/or minutely pseudolepidote.
- Morphology Stem
- Trunks occasionally stilt-rooted. Twigs stout, often with pronounced leaf scars, producing an exudate when cut, which hardens and darkens on drying.
- Morphology Leaves
- Leaves alternate, usually crowded towards the end of the twigs, petiolate or subsessile, stipulate or not; blades simple, often obovate, entire, penninerved.
- Morphology Reproductive morphology Inflorescences
- Inflorescences axillary, or borne on older wood, solitary or fasciculate, pedunculate, with a whorl of 5–12 involucrate imbricate tepaloid bracts surrounding the flowers; male inflorescences many-flowered, the flowers in dense globose capitula; female inflorescences 1-flowered.
- Morphology Reproductive morphology Flowers
- Male flowers sessile; calyx campanulate or turbinate, truncate, dentate or irregularly or regularly lobed, the lobes imbricate; petals absent; disk absent; stamens (4)5(6), free, episepalous, anthers erect, subbasifixed, introrse, thecae parallel, longitudinally dehiscent; pistillode cylindric-obconic, infundibuliform, hypocrateriform, pileiform or sometimes lobed. Female flowers sessile; calyx minute, truncate, sinuate or lobed, disciform; petals absent; disk absent; ovary (2)3(5)-locular, with 2 ovules per loculus; styles (2)3(5), free, thick, recurved, covering the ovary, multipartite to laciniate.
- Morphology Reproductive morphology Fruits
- Fruit drupaceous, indehiscent; mesocarp spongy; pyrenes (2)3(4), dorsally carinate and bisulcate, indurate, tardily bivalved.
- Morphology Reproductive morphology Seeds
- Seeds mostly 1 per pyrene, compressed, ecarunculate; endosperm fleshy; embryo straight; cotyledons broad, flat, green.
