Descriptions

Boraginaceae, E. S. Martins (Trichodesma by R. K. Brummit). Flora Zambesiaca 7:4. 1990

Morphology General Habit
A shrub or sometimes a small tree up to 5(10) m. high; branches pubescent with moderately dense short hairs, sometimes with a few longer glandular hairs.
Morphology Leaves
Petiole 2–6(9) cm. long, slender, canaliculate, pubescent, the hairs spreading or ± appressed, sometimes with some glandular hairs as on the branches; leaf-lamina 6–10( 17) x 3–7( 12) cm., ovate to obovate, pubescent above, sometimes only on the nerves, or subglabrous, pubescent to almost velvety or shortly woolly below, subacute to rounded and apiculate at apex, subacute to rounded and often ± asymmetrical at base, margins entire, papery to almost leathery, with 6–8 nerves on each side of the midrib, net-veined.
Morphology Reproductive morphology Flowers
Flowers arranged in panicles 7–13 cm. long, lax, bracteate, terminal, with indumentum similar to the branches and petioles; bracts falling; pedicels up to 3 mm. long, joined at the apex.
Morphology Reproductive morphology Flowers Calyx
Calyx 3.0–3.5 mm. long, pubescent outside, glandular hairs absent; lobes triangular, acute, as long as the tube.
Morphology Reproductive morphology Flowers Corolla
Corolla 3.5–4.5(5) mm. long, glabrous, whitish; tube 3.0–4.0 mm. long, narrowly campanulate; lobes 1.0–1.4 x 1.2–1.8 mm., much broadly ovate, obtuse to rounded, erect to spreading.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens inserted about the middle of the corolla tube, included; anthers 0.8–1.2 mm. long, subsessile.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary c. 1 mm. long, conical; style 1.5–2.5 mm. long, very shortly bifid, included; stigmas large, ± peltate.
Morphology Reproductive morphology Fruits
Fruit c. 5 x 6 mm., a little depressed, usually topped by the persistent style; pyrenes with 6–8 lamellae on the outer surface.

Morphology General Habit
Almost identical with the last, save for the velvety pubescence on the stems, undersides of the leaf-blades, inflorescence-axes, calyx, etc. and sometimes few to many additional glandular hairs.
Morphology Leaves
The leaf-blades can be rather larger, up to 18 cm. long, 8 cm. wide, sometimes acuminate at the apex, subcordate or cordate at the base but mostly cuneate to rounded.
Morphology Reproductive morphology Inflorescences
The inflorescences are also often rather more extensive with secondary peduncles up to 8 cm.
Habitat
Lowland forest, woodland, bushland, thicket on coral, also in cultivations; 0–600 m.
