Type: South Africa, Transkei, between Umtenta and Umzimkulu Rivers, Drège s.n. (BM!, lecto K!, isolecto.)
Morphology General Habit
Aromatic shrub to 1 m tall; 0.3–1.5 m elsewhere
Morphology Stem
Stems erect, quadrangular, brittle, sometimes arising from a small woody rootstock but this lacking tuberous roots, branching above, pubescent with patent glandular and eglandular hairs
Morphology Leaves
Leaves petiolate; blades ovate to elliptic, 3–7 × 1.1–4 cm, serrate with serrations minutely apiculate, apex acute to obtuse, base truncate or broadly cuneate, sparsely pubescent and with sessile glands; petioles 5–15 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax, with 2–4-flowered verticils 5–10 mm apart; bracts narrowly ovate, 1 mm long, erect above forming an inconspicuous apical coma; pedicels 3 mm long, terete, spreading
Morphology Reproductive morphology Flowers Calyx
Calyx 2 mm long at anthesis; fruiting calyx shortly tubular; throat open in fruit, glabrous, 4–7 mm long; teeth of anterior lip lanceolate, posterior margin of lateral lobe not extended towards the posterior lip
Morphology Reproductive morphology Flowers Corolla
Corolla white, 4–5 mm long, 4–8 mm long elsewhere; tube 4 mm long, straight, dilating at throat; 4-lobed, posterior lobe emarginate

Nutlets not seen, elsewhere 2 mm long, narrowly ovoid in outline, triangular in cross-section, truncate, glabrous or with few hairs at apex.
Ecology
Brachystegia thicket; 550 m
Conservation

Note
Similar in habit to E. usambarensis but differing chiefly in much shorter, white corollas. Differs from E. villosus in shorter, white rather than pink corollas and in a smaller rootstock lacking tuberous roots. The only specimen recorded from East Africa, on which the above description is based, differs from specimens found from Zambia, Mozambique and further south by its fewer-flowered verticils and larger leaves.
