Rhizophoraceae, A. R. Torre & A. E. Gonçalves. Flora Zambesiaca 4. 1978

Morphology General Habit
Wholly glabrous evergreen shrubs or medium-sized trees of muddy sea-shores and estuaries; stems with appressed stilt-roots, forming, with the lower part of the trunk, a ± pyramidal base; pneumatophores present as upright projections from the mud.
Morphology Leaves
Leaves decussate, crowded at the apex of the twigs, petiolate, stipulate; leaf-lamina entire, leathery, with the nerves obscure on both faces.
Morphology Reproductive morphology Inflorescences
Inflorescences (2)4–8(10)-flowered, cymose, condensed, solitary, axillary, towards the upper part of the branches.
Morphology Reproductive morphology Flowers
Flowers bisexual, subsessile to sessile, with cupular, partly connate pairs of bracts disposed beneath each flower and each cluster.
Morphology Reproductive morphology Flowers Calyx
Calyx glabrous, persistent; calyx-tube adnate to the ovary; calyx-lobes (4)5(6), spreading in fruit.
Morphology Reproductive morphology Flowers Corolla
Petals emarginate or truncate, fringed or with (2)3 long-stipitate clavate glands above, sometimes cohering from the middle towards the base by the uncinate-hairy margins, inserted at the mouth of the calyx-tube, each embracing 2 stamens.
Morphology Reproductive morphology Flowers Disc
Disk shallowly (8)10(12)-lobed, cupuliform.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens twice as many as the petals, inserted in the sinuses of the disk; filaments unequal to ± equal in each pair; anthers ± ovoid.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary semi-inferior, 3-locular, each locule 2-ovulate; style simple, terete and conical below, minutely 2–3-lobed to entire at the apex.
Morphology Reproductive morphology Fruits
Fruit an ovoid, leathery, indehiscent, unilocular, usually 1-seeded berry, mostly superior; seed germinating on the plant, the radicle developing a clavate, ridged and sulcate hypocotyl tapering to the apex, which perforates the apex of the fruit and falls out of it.
