Bridelia Willd.

Genus

Angiosperms > Malpighiales > Phyllanthaceae

Characteristics

Monoecious or rarely dioecious shrubs or trees with a simple indumentum. Branches sometimes armed with blunt woody thorns. Twigs lenticellate. Leaves alternate, shortly petiolate, stipulate, simple, usually entire, penninerved, the nerves straight, arched or looped, the tertiary nerves usually parallel. Flowers small, axillary, solitary, glomerulate or fasciculate, or in spikes or panicles of glomerulate fascicles. Bracts small, scaly. Male flowers in many-flowered glomeruli, sometimes with 1–2 ♀ flowers admixed, sessile or subsessile; sepals 5, valvate; petals 5, small, inflexed over the disc or quincuncially imbricate; disc annular or cupuliform, entire or sinuate; stamens 5, filaments united below into a short column, free and spreading above, anthers horizontal, basifixed, the thecae parallel, longitudinally dehiscent; pistillode at the top of the staminal column, ampulliform, entire or 2–4-lobate. Female flowers in few-flowered clusters or solitary, sometimes pedicellate; sepals and petals perigynous, otherwise ± as in the male; outer disc annular, inner disc lobed or cupular and embracing the ovary; ovary 2(–3)-locular, with 2 ovules per locule; styles 2(–3), free or connate at the base, bifid or subentire. Fruit a small, smooth, ovoid or globose berry or drupe, indehiscent, or else dehiscent; exocarp fleshy or pulpy; endocarp crustaceous, forming 2 (or by abortion 1) pyrenes. Seeds often by abortion solitary in each pyrene, plano-convex and adaxially longitudinally grooved (2 pyrenes) or else U-shaped in transverse section and adaxially deeply excavate (1 pyrene); albumen copious, fleshy; embryo slightly or strongly curved; cotyledons broad, foliaceous, thin.

Fruits drupaceous, ellipsoid to globose, with surface smooth, indehiscent. Seeds 1 or 2 per fruit; ovoid to semi-ovoid; testa smooth; albumen fleshy or membranous; ecarunculate; cotyledons broad, flat.
Trees, shrubs, rarely woody lianas. Leaves simple, alternate, entire, pinnately veined, petiolate, stipulate. Flowers small, unisexual, monoecious, few to many flowers grouped into axile glomerules, pedicellate or sessile. Sepals 5, valvate. Petals 5, scale-shaped. Male flowers: stamens 5; filaments connate at base, forming staminal column, apical free and extended filaments surrounding rudimentary ovary; anthers dorsifixed, introrse, 2-loculed, parallel, longitudinally dehiscent; rudimentary ovary terete or obovate, sometimes conical, 2-4-fid at apex; disk cup-shaped or discoid. Female flowers: disk pulvinate or saucer-shaped lining flower with a conical or urceolate part, surrounding ovary, tearing as ovary expands; ovary 2-loculed; ovules 2 in each cell; styles 2, free or connate at base, bifid or entire at apex. Drupes or rarely capsules with fleshy epicarp, 1-or 2-celled (putamens). Seeds 1 or 2, with longitudinal groove; embryo curved; endosperm copious; cotyledons thin, large. x = 13.
Male flowers in many-flowered fascicles, sometimes with 1–2 female flowers admixed, sessile, subsessile or shortly pedicellate; sepals (4)5, valvate; petals 5, small, inflexed and not contiguous or imbricate; disk annular or cupuliform, entire or sinuate; stamens 5, filaments united below into a short column, free and spreading above, anthers horizontal, basifixed, the thecae parallel, longitudinally dehiscent; pistillode at the top of the column ampulliform, entire or 2–4-lobed.
Seeds solitary per locule by abortion, plano-convex and longitudinally grooved in 2-locular fruits, C-shaped in transverse section and hollowly cylindrical, split down one side in 1-locular fruits; albumen copious, fleshy; embryo curved; cotyledons broad, foliaceous, thin.
Female flowers few per cluster or solitary, sometimes pedicellate; sepals and petals perigynous, otherwise ± as in female; outer disk annular, inner encasing the ovary; ovary 2(3)-locular, ovules 2 per locule; styles 2(3), free or connate at the base, bifid or subentire.
