Type
Type: Yemen [Arabia Felix], Botta s.n. (P, holo.)
Morphology General Habit
Aromatic annual or short lived perennial woody herb, 15–20 cm tall with one or several stems arising from a tap root
Morphology Stem
Stems erect, quadrangular, much branched, woody at base, pubescent with short or long, patent eglandular and glandular hairs often with longer hairs at nodes and with sessile glands
Morphology Leaves
Leaves sessile, often with fascicles of young leaves in axils; blades linear, narrowly elliptic or narrowly obovate, 8–15 × 2–4 mm, distally crenate, often slightly revolute, apex round or obtuse, base attenuate or cuneate, glandular-punctate and pubescent with hairs denser on younger leaves
Morphology Reproductive morphology Inflorescences
Inflorescence lax, with 2-flowered verticils 7–10 mm apart; bracts 1 mm long, with long white hairs; pedicels 2 mm long, erect or ascending, slightly flattened, curving distally
Morphology Reproductive morphology Flowers Calyx
Calyx horizontal, 3 mm long at anthesis, pubescent with longer hairs on anterior teeth and veins, sometimes with sessile glands; fruiting calyx tubular-campanulate with throat open with a dense ring of villose hairs, 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 pink with white tube, (7–)10–15 mm long; tube 8 mm long, slender, parallel-sided, dilating at throat; 4lobed or posterior broader and emarginate to bifid
Morphology Reproductive morphology Fruits
Nutlets black, ovoid, rounded at apex, 1.5–2 mm long, smooth producing copious greyish mucilage when wet.
Ecology
Open Acacia-Commiphora scrub, on limestone; 420–850 m
Conservation
Least Concern; widespread in Arabian Peninsula, Africa and southern Madagascar, but in East Africa relatively few collections, often from areas of limestone
Note
Perhaps most closely related to E. glandulosus R.M.Harley & Sebsebe from Ethiopia, which has a more spreading habit, shorter inflorescence and 5-lobed corolla.
