Trichocladus Pers.

Genus

Angiosperms > Saxifragales > Hamamelidaceae

Characteristics

Trees or shrubs, mostly with conspicuous stellate indumentum. Leaves alternate or opposite, simple, usually entire but ± toothed in one species; stipules small. Flowers in dense terminal or axillary round heads, hermaphrodite or sometimes only ♀. Calyx-tube shallow or campanulate, sometimes adnate to the ovary, lobes (3–)4–5, broadly triangular, valvate. Petals 4–5 or often absent in ♀ flowers, linear-spathulate, much longer than the calyx, often free at base, valvate or slightly imbricate, at first sometimes rolled up or folded in the bud, later sometimes with revolute margins. Stamens as many as the petals; filaments usually shorter than the anthers, turbinate or obpyramidal; anthers opening by valves, mostly beaked; staminodes absent. Ovary inferior to almost superior, 2-locular; ovules pendulous, solitary in each cell. Capsule subglobose, (l–)2-locular, 2-valved, but appearing 4-valved at apex after dehiscence. Seeds ellipsoid or ovoid-oblong, the hilum divided into 2 areas extending from proximal end of the seed on each side; embryo large, the cotyledons well developed.

Leaves opposite or alternate, ovate-cordate to oblong, usually entire, sometimes peltate at the base, petiolate; stipules linear or subulate, inconspicuous.
Stamens as many as and alternating with the petals; filaments short and thick; anthers basifixed, usually mucronate or beaked, opening by lateral valves.
Petals 4–5, linear-spathulate, greatly exceeding the calyx, with margins revolute, usually valvate, stated to be absent from female flowers.
Fruit a woody loculicidally 2-valved capsule, with bony and elastic endocarp which in dehiscence separates from the epicarp.
Ovary inferior to almost superior; styles 2, free, often recurved, persistent; ovules 1 in each loculus, apical, pendulous.
Seeds ellipsoid to oblong-ovoid, with a large apical hilar area; cotyledons large; endosperm scanty.
Flowers in small dense terminal or axillary capitula or spikes, bisexual or sometimes female only.
Calyx-tube adnate to the base of the gynoecium; calyx-lobes 4–5, valvate.
Evergreen trees or shrubs, mostly with conspicuous stellate indumentum.
