Information
Procumbent or spreading shrub, branching from ground level or occasionally along the stems; young branches yellowish-pubescent. Leaf-lamina 3·5–9 × 2·5–7·5 cm., very broadly oblong, rounded, acute or acuminate at the apex, margin serrate, truncate or subcordate at the base, upper surface bronzed when dry, sparsely appressed-pubescent, more densely pubescent beneath; nerves rather prominent below; petiole 2–3 mm. long, densely pubescent; stipules c. 5 mm. long, subulate, entire or more usually bifid, pubescent. Inflorescences all axillary with 3–5 cymes often crowded in one axil, on thinly pubescent peduncles up to 1·5 cm. long; pedicels similar, up to 5 mm. long; bracts deeply bifid, trifid or occasionally simple, pubescent. Flower-buds oblong, not swollen at the base, somewhat longitudinally sulcate. Sepals c. 7 mm. long, linear-oblong, densely and closely pubescent on the back, glabrous and reddish-yellow within. Petals yellow, somewhat shorter than the sepals, linear-oblong, often bidentate or incised at the apex, with a basal nectariferous claw circumvillous on the margins within setose-pubescent on the back and with a slight ledge above on the inside. Androgynophore 1 mm. long, glabrous, barely elongated above the node but tomentose at the apex and not clasping the ovary-base. Ovary ovoid, not lobed, setose-pubescent; style up to 6 mm. long, glabrous; stigma-lobes 4, short, subulate. Fruit c. 8 mm. in diam., yellowish when ripe, globose or obovoid, finely appressed-stellate-hairy, not lobed.

Notes
Although this species has been confused with G. flavescens Juss., its dwarf habit is quite distinctive and a further minute but important difference is that the androgynophore is in fact very slightly elongated. It therefore falls rather artificially in Burret’s Subsect. Apodogynae with G. flavescens etc. when it would be better placed with G. falcistipula K. Schum. in the Podogynae. The divided bracts of this species point to the same affinity.Grewia trothai Burret to which Hutchinson (loc. cit.) refers Hutchinson &? Gillett 3560 (K) is an unpublished MS name based on von Trotha 25a from Windhoek, SW. Africa. Burret later (in Engl., Bot. Jahrb. 45: 166 (1911)) referred this latter specimen to G. olukondae Schinz.
