Names
Abutilon fruticosum Guill. & Perr. [family MALVACEAE], in Guill., Perr. & Rich., Fl. Senegamb. Tent. 1: 70 (1831). — Mast. in Oliv., F.T.A. 1: 187 (1868). — Eyles in Trans. Roy. Soc. S. Afr. 5: 412 (1916). — Burtt Davy, F.P.F.T. 2: 275 (1932). — Exell & Mendonça, C.F.A. 1, 1: 153 (1937); tom. cit., 2: 373 (1951). — Brenan, T.T.C.L.: 298 (1949). — Keay, F.W.T.A. ed. 2, 1, 2: 337 (1958). TAB. 93 fig. 5. Type from Senegal.
Information
Shrub 0·5–1·25 (2) m. tall, much branched, canescent to glaucous-grey with a dense very short velvety indumentum; stems terete, slender, at length glabrescent, woody and ultimately covered with a light brown or greyish bark with short darker linear markings. Leaf-lamina 2–6 (10) × 1·5–4 (6) cm., apex obtuse to acute or somewhat acuminate, margin usually subentire to slightly crenate or serrate, less often more conspicuously serrate, upper surface grey-green with indistinct venation, lower surface paler and canescent with distinct somewhat prominent venation; petiole somewhat shorter or slightly longer than the corresponding lamina. Flowers solitary on the main branches and/or on short leafy axillary shoots; pedicels 0·5–4 (8) cm. long, slender, terete, articulated near the apex. Calyx 5–6 mm. long, broadly campanulate to cupular, divided to about the middle; lobes triangular or triangular-ovate, mucronate, minutely ciliate, with indistinct median vein. Petals 7–10 mm. long. Staminal tube stellate-hairy. Fruit 8 × 10–12 mm., broadly cylindric with rounded base, widely and shallowly umbilicate. Mericarps usually c. 10, broadly keeled in apical half (hence fruit in upper half characteristically furrowed between the mericarps), obliquely truncate-convex at the apex with the dorsal angle subacute to shortly mucronate but not awned, when not yet ripe densely and shortly greyish-green, ultimately grey-brown, stellate-tomentose dorsally and on the apical dorsal area of the flat sides, not turning black. Seeds usually 3, c. 1·5 × 1·5 mm., usually greyish-brown, minutely verruculose-punctate.
Habitat
In xerophilous low scrub and in wooded grassland vegetation, often-on alkaline soil, but also on rocky slopes and gravelly soil; rarely in riverine bush on silt; usually in regions with a low annual rainfall.
Range
Widely spread in all the drier areas of the western half of Africa from Senegambia to SW. Africa, in the Transvaal and also from Kenya to Egypt and from Arabia to India
Distribution
Zimbabwe S Beitbridge, fr. 22.iii.1959, Drummond 6145 (K; SRGH).Botswana N Ngamiland, Kwebe Hills, fl. & fr. 4.i.1898, Lugard 85 (GRA; K).
Notes
This is the only species of Abutilon in southern Africa the flowers of which open in the morning.
