Type
Type: Tanzania, Morogoro District: ± 19 km NE of Turiani, Drummond & Hemsley 1819 (K!, holo.)
Morphology General Habit
Aromatic viscid perennial herb to 30 cm tall with several stems arising from a woody rootstock
Morphology Stem
Stems quadrangular, ascending or erect, branched, woody at base, often with the epidermis peeling below, pubescent or villous with patent glandular and eglandular hairs and with sessile glands
Morphology Leaves
Leaves petiolate; blades ovate to broadly ovate or oblong, 0.6–2.5 × 0.6–1.7 cm, serrate or crenate, apex rounded, base cuneate or broadly cuneate, pubescent or villous with long glandular and eglandular hairs; petioles 2–20 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax with (2–)4–6-flowered verticils 0.5–2 cm apart; bracts small, 1–2 mm long, often with long white hairs especially on margin, erect above forming an inconspicuous terminal coma; pedicels 2–2.5 mm long, slightly flattened, curved distally
Morphology Reproductive morphology Flowers Calyx
Calyx 2–2.5 mm long at anthesis, pubescent with patent glandular and eglandular hairs on base and teeth margins, densely villous at throat; fruiting calyx tubular-campanulate with throat open with a dense ring of villose hairs, 4–5 mm long; lateral lobes of calyx anterior lip deltate or lanceolate with the posterior margin extended towards the posterior lip; median lobes of anterior lip linear, longer than lateral teeth
Morphology Reproductive morphology Flowers Corolla
Corolla white or pale pink, 4–8 mm long; tube 3.5–6 mm long, straight, parallel-sided, dilated at throat, 4-lobed, posterior lobe emarginate or entire
Morphology Reproductive morphology Fruits
Nutlets brown, 1.5 mm long, ovoid with apex rounded, producing a small amount of mucilage when wet
Figures
Fig 33: 1–2, p 200
Ecology
Grassy places, rock outcrops and streamsides in costal and deciduous bushland and Brachystegia woodland; 15–900 m
Conservation
Least concern; quite widely distributed in the coastal region of three countries
Note
E. obbiadensis (Chiov.) Ashby from Somalia is also very similar to E. albus, but it seems to differ in being annual and having a purple corolla. E. albus is most likely to be confused with E. wakefieldii. The main difference is the stem indumentum, E. wakefieldii having mainly antrorse and scattered patent eglandular hairs and no glandular hairs on the stem below the inflorescence axis, whereas E. albus has patent glandular and eglandular hairs, There is also usually a difference in corolla colour: white in E. albus, pink in E. wakefieldii. However, Harvey et al. 47 is reported as having very pale ink or mauve corollas. E. albus also tends to be erect in habit rather than prostrate as in E. wakefieldii.
