Species

Angiosperms > Malvales > Malvaceae > Hermannia

Characteristics

Perennial, bushy, much branched from base, 30-60 cm tall; branches and branchlets pubescent with 1-to several-celled glandular hairs and many gland-tipped hairs intermixed with some long, patent, pointed hairs. Stipules 0.75-2 mm long, up to 1 mm broad. Leaves petiolate; blade on upper branches more or less narrowly oblong, very variable in size and on some branches much reduced, ranging from about 6 mm x 1.5 mm to 30 x 14 mm, rounded or shortly cuneate at base, usually broadly acuminate towards apex, margins serrate, coarsely and usually sparsely stellate-pubescent on both surfaces, with some glandular hairs intermixed and sometimes gland-tipped hairs present as well, especially along margins and with numerous, minute papillae on the surfaces, petiole 1.5-15 mm long, the lower longer. Inflorescence of 1-flowered cymes in axils of leaves, solitary but appearing racemose in specimens where leaves on ultimate branches are much reduced; peduncle usually short, 5-14 mm long, occasionally (as in the type) up to 25 mm long, persistent, 2-3-bracteate at apex (bracts under 1 mm long), pubescent with glandular or gland-tipped hairs and sometimes with long, pointed, patent hairs intermixed; pedicels 2-4 mm long, pubescence like that on peduncles. Calyx about 7 mm long, lobed to beyond middle, pubescent on outside mainly with glandular hairs, but sometimes stellate hairs present and long non-glandular pointed hairs as well; lobes pubescent inside with appressed, non-glandular hairs. Petals pale pink to pale violet, sometimes with a red base, narrowly oblong-cuneate or suborbicular-cuneate, 2-6 mm long, 1-2.5 mm broad in upper half, margins inrolled in lower half only, auricles thickened and infolded with a thickened ridge between them, auricles and ridge densely to laxly setose. Stamens from about 6 to 10 mm long; filaments up to 4 mm long, hyaline, obovate, setose on shoulders; anthers up to 8 mm long, erect, pointed, overlapping filaments at base, sparsely patently pubescent (on a few specimens anthers aborted, blunt, about 1.5 mm long). Ovary stipitate at base (stipe up to 1.5 mm long), pubescent with short glandular hairs and with pointed setae along the sutures. Capsule up to 7 mm long and about as wide, glandular-hairy on surface between sutures, setae along sutures, blunt or with horns eventually up to 2 mm long; seeds more or less reniform, corrugated, granular and with minute papillae.
More
Leaf-lamina up to 5·5 × 2·3 cm. but usually less, lanceolate to narrowly oblong-lanceolate, apex acute or subacute, margin serrate, base cuneate or rounded, pilose on both surfaces with appressed stellate hairs and some glandular hairs; petiole up to 1·4 cm. long; stipules 1–2 mm. long, lanceolate-subulate.
Shrublet, up to 0.6 m high. Branchlets with many patent, gland-tipped hairs intermixed with long, pointed, patent hairs. Inflorescence a 1-flowered cyme in axils of leaves. Capsule glandular-pubescent between sutures, glabrescent. Flowers pale pink to pale violet.
Petals c. 4–5 × 3 mm., pink, red or rarely whitish, obovate, apex denticulate, retuse or truncate, margin subauriculate and inrolled in the lower half, pilose across the opening created by this inrolling.
Ovary shortly stipitate, narrowly obovoid, densely glandular with a few hispidulous hairs at the apex and on the ribs; styles c. 5 mm. long, pubescent and glandular except near the apex.
Perennial herb or shrublet, up to c. 1 m. tall, viscid-pubescent with glandular hairs on all parts except the corolla but also with long simple hairs and stellate hairs.
Capsule c. 8 × 7 mm., oblong-obovoid, densely glandular but hispidulous on the ribs, with short spreading horns c. 1·5 mm. long at the apex.
