Perennial herb with solitary or a few erect unbranched or sparsely branched stems from a slender creeping rootstock; stems up to 45 cm long, antrorsely sericeouspuberulent to -puberulous when young
Morphology Leaves
Leaves with strongly raised rib-like veins; lamina elliptic or narrowly so, largest 2.8–7 × 0.8–1.6 cm, apex subacute to rounded, glabrous to sparsely puberulous (densest along veins) when mature and finely ciliate
Morphology Reproductive morphology Flowers
Flowers in condensed 3–7-flowered axillary cymes which are congested towards end of branches and ± concealed under leaves and bracts; peduncle and branches up to 2 mm long; outer bracts elliptic to obovate, up to 2 cm long; inner bracts and bracteoles linear to oblanceolate, up to 1.5 cm long
Morphology Reproductive morphology Flowers Calyx
Calyx 8–15 mm long, glabrous to sparsely puberulous; teeth 4–8 mm long, longer than or same length as tube, finely ciliate
Morphology Reproductive morphology Flowers Corolla
Corolla indistinctly 2-lipped, pure white or with pale yellow throat, sparsely puberulent, 11–18 mm long of which the linear tube 4–8 mm, the throat 3–6 mm and the limb 2–4 mm; lobes subequal (fused higher up in upper lip and middle in lower lip slightly wider), recurved in mature flowers. Free part of filaments 2–4 mm long, hairy in basal part, glabrous upwards; anthers ± 1 mm long, muticous at base but not spurred

Ecology
Brachystegia and Brachystegia-Uapaca woodland on red loam; 850–1700 m
Note
A very distinctive species easily recognised by its small white flowers with muticous anthers, by the condensed inflorescence more or less covered by leaves and bracts, and by the strongly raised rib-like leaf-veins. D. mutica sensu C.B.Clarke in Fl. Cap. 5: 16 (1901) is a quite different species.
