Bruguiera cylindrica (Rhizophoraceae)

[FZ]

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

Morphology Reproductive morphology Flowers Calyx
Calyx glabrous, leathery, accrescent; calyx-tube adnate at the base to the ovary; calyx-lobes 8–15.
Morphology Reproductive morphology Flowers Corolla
Petals 2-fid and apically setigerous, involute at the base (each embracing a pair of stamens), nor clawed, inserted at the mouth of the calyx-tube.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens twice as many as the petals, epipetalous; filaments unequal in length in each pair, filiform; anthers linear, dehiscing longitudinally.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary inferior, 2–4-locular, each locule 2-ovulate; style filiform, with 2–4 minute stigmatic lobes.
Morphology Reproductive morphology Fruits
Fruit a leathery, indehiscent, usually unilocular, mostly 1-seeded berry, included in and adnate at the base to the calyx-tube; seed germinating on the plant, the radicle developing a ± terete or obscurely ribbed, blunt hypocotyl, which perforates the fruit-apex and falls with the fruit; cotyledons minute and connate at the base.
Morphology General Habit
Wholly glabrous and evergreen shrubs or trees of muddy sea-shores and estuaries, with geniculate pneumatophores arising from the mud, sometimes with aerial roots when young; roots and lower part of the trunk forming a pyramidal buttressed base.
Morphology Leaves
Leaves decussate, petiolate; leaf-lamina entire, leathery, usually black-dotted beneath, with the nerves obscure to visible below and visible or distinct above; stipules large, lanceolate.
Morphology Reproductive morphology Inflorescences
Inflorescences 1-few-flowered, cymose, axillary; peduncles usually arched outwards.
Morphology Reproductive morphology Flowers
Flowers bisexual, ebracteolate.

Morphology Reproductive morphology Flowers Gynoecium Pistil
