    Habit
    Low perennial suffrutex, much branched and woody at the base, up to 30 cm., rarely up to 60 cm. tall; stems usually branched throughout, terete or somewhat angled, usually greyish-green or greyish (rarely brownish), shortly and densely tomentose-velutinous, the upper portions usually slender and wiry.
    Leaves
    Leaf-lamina 2–4 × 1–2·5 cm., usually ovate-oblong to oblong but occasionally narrower or broader, apex subacute, margin irregularly rather coarsely serrate, base generally cuneate or more or less rounded, the upper surface dark green or brownish-green, usually sparsely and minutely stellate-pubescent, glabrescent, lower surface usually much paler, greyish- or yellowish-green, densely velutinous-tomentose and with prominent veins; petiole 3–10 mm. long, tomentose-velutinous; stipules 4 × 1 mm., ovate-lanceolate to lanceolate, velutinous, sometimes somewhat falcate, rather persistent.
    Flowers
    Flowers deep yellow to orange, occasionally paler, solitary, axillary; pedicels 3–6 cm. long, slender, terete, velutinous or tomentose, articulated near the apex.
    Calyx
    Calyx c. 8 mm. long, obconical-campanulate to saucer-shaped, tomentose outside, and along the margin inside, incised to about the middle; lobes triangular, somewhat narrowed or acuminate at the apex, 5 mm. broad at the base, with the median vein pinnately branching at about the middle of the lobe.
    Corolla
    Petals c. 10 × 8 mm., finely pubescent outside with simple hairs.
    Stamens
    Staminal tube with stellate hairs (usually sparse).
    Fruits
    Mericarps 7–9, c. 4 × 3 mm., muticous or subacute at the apex, usually stellate-hairy at the apex only, reticulate-veined on the flat lateral sides.
    Seeds
    Seeds brown, glabrous except for a small tomentose area around the hilum.

    Type
    Type: Namibia, Hereroland, North foothills of Auas Mts, Dinter 1877 (B†, holo.)
    Habit
    Perennial spreading or prostrate herb or much branched subshrub 30–70 cm tall or long.
    Stem
    Stems branched, shortly mostly densely velvety pubescent
    Leaves
    Leaves narrowly to broadly ovate-oblong or oblong, 1–4 × 0.5–2.5 cm, ± acute to rounded at the apex, cuneate to ± rounded at base, rather coarsely serrate, darker green above with sparse to ± dense stellate pubescence, usually much paler beneath, densely to very densely velvety stellate-pubescent and with prominent venation; petiole 2–10 mm long, stellate-pubescent; stipules ovate-lanceolate to lanceolate, 2–4 × 1 mm, pubescent
    Flowers
    Flowers solitary, axillary; pedicel 1.3–6 cm long, much longer than subtending petiole, pubescent, jointed near apex; calyx obconic-campanulate, ± 8 mm long, densely stellate-tomentose outside, base strongly ribbed and drying yellowish, divided to ± middle into broadly triangular lobes, 5 mm wide at base, acute to acuminate at apex
    Corolla
    Corolla yellow to orange or white; petals 10 × 8 mm.
    Stamens
    Staminal tube with ± sparse stellate hairs
    Fruits
    Mericarps 6–8(–9), 4 × 3 mm, subacute (the awns totally fused or obscure) and stellate-pubescent at apex, reticulately veined on back and flat sides, not splitting at base, the awn beaks totally fused or often separating into two divisions resembling thick awns and often each with a short true awn at end.
    Ecology
    Coastal grassland, wooded grassland and bushland with Combretum, Xeroderris, Pteleopsis, Terminalia etc. on rocky hills above Commiphora–Acacia bushland, roadsides, also on black cotton soil in old cultivations; 0–1400 m
    Note
    A distinctive totally prostrate plant ( Luke 6144, Lamu District: Kiwayu KWS/WWF Camp, 2 Jan. 2000) which the collector could not match at EA and I first thought was a subspecies of S. calliantha Thulin from S Somalia, is I think only a form of S. chrysantha. Rather similar prostrate forms occur in Tanzania. The BM duplicate of Hildebrandt 910 bears a pencil annotation ‘ Sida longipes E.Mey.? fide Garcke’ but I have not discovered if this determination was published. Sida longipes E.Mey. ex Harv., non A. Gray is now called S. dregei Burtt Davy.
