Type
Type: N Yemen, Hadie and Srd, Forsskål s.n. (BM!, holo.; C, iso.)
Morphology General Habit
Aromatic perennial herb, 15–100 cm tall
Morphology Stem
Stems rounded-quadrangular, much branched, branches often twiggy, woody at base, with epidermis often tearing in strips below; indumentum of short appressed or retrorse hairs becoming denser on the inflorescence-axis
Morphology Leaves
Leaves rarely with fascicles of young leaves in axils; blade narrowly ovate or linear, 2–6 × 1–3.5 cm, entire or shallowly serrate, apex acute or obtuse, base cuneate, with all over indumentum of short, appressed hairs or with hairs restricted to veins beneath, glandular-punctate; petiole 3–18 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax, verticils 8–12 mm apart; bracts green or reddish-mauve, erect above forming a small apical coma or not, deciduous or not, petiolate, elliptical, acute at tip, 3–7 mm long, ± 3 mm broad, densely pubescent; pedicels ± 3 mm long, ± erect, slightly flattened and curved
Morphology Reproductive morphology Flowers Calyx
Calyx ± downward-pointing, 4 mm long at anthesis, indumentum of tube hoary or densely pubescent, hairs often pinkish, posterior lip ± glabrous, anterior lip pubescent, gland-dotted, interior with a dense ring of hairs at throat; posterior lip rounded at tip, decurrent, median teeth of anterior lip lanceolate, acuminate, lateral lobes deltate, cuspidate; fruiting calyx 6–8 mm long, throat open, posterior lip accrescent, wider at tip, decurrent, median and lateral teeth of anterior lip ± convergent
Morphology Reproductive morphology Flowers Corolla
Corolla off-white, white marked with purple or pale pink, 6–10 mm long; tube straight, funnel-shaped, 1.5–2 times longer than calyx tube
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens exserted 3–6 mm, posterior with a large, fleshy, flattened, ± glabrous outgrowth near base
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous
Morphology Reproductive morphology Fruits
Nutlets grey-black, ovoid, 1.5 mm long, smooth, mucilaginous when wet.
Ecology
Acacia-Commiphora bushland and dry scrub; 100–1350 m
Conservation
Least concern
Note
Some material from the Mandera area and from Turkana agrees with material from Ethiopia attributed to O. stirbeyi in having narrow folded leaves and a tendency to have clusters of smaller leaves in the axils. This form seems to intergrade with the more common form of the species.
Distribution
Range: Sudan, Eritrea, Ethiopia and Somalia, Egypt, Saudi Arabia, Yemen, Oman Flora districts: K1 K4 K7
