Information
Subshrub, perennial or annual herb, usually with only one stem, 0.15–1 m tall, with simple hairs only. Leaves petiolate; blade lanceolate, elliptic, narrowly ovate or narrowly obovate, up to 10–50 × 3– 20 mm, apex rounded to acute, base cuneate, margin serrate or subentire. Inflorescence ± lax; bracts early deciduous with the scars forming ± dark bowl-like glands. Fruiting calyx 5–9 mm long, closed by the lateral lobes pressing together, with a ventral constriction in the tube; upper lobe 3.5–5 mm broad, narrowly cuneate at the base; lateral lobes with the posterior margin extended, ± arcuate, ± ciliate, often with a few small teeth near apex; lower lobes subulate, separated from the lateral lobes by a very shallow sinus. Corolla 8–13 mm long, white or rarely pale reddish or lilac. Anterior stamens 5–12 mm longer than the lower lip of the corolla; anthers with parallel thecae. Nutlets c. 1.5–1.6 × 1.1–1.3 mm, smooth, pale brown, producing mucilage when wet.
Range
N1–3; C1, 2, S1–3 Arabian peninsula, India to Sri Lanka and Burma, and widespread from Sudan, Eritrea, Djibouti and Ethiopia to southern Africa and Angola.
Altitude range
10–1350 m.
Distribution
SOMALIA Thulin & Warfa 4489; Friis & al. 4683; Wood S/72/53.
Notes
Sebald (1989) cited Raimondo 36/76 from dunes near Mogadishu (S2) as O. obovatum E. Meyer ex Benth. This collection has not been seen, but it is believed to belong to O. filamentosum, a common species in the Mogadishu area. The material from dunes near Mogadishu differs from other Somali O. filamentosum by having broader leaves, and may resemble O. obovatum by appearing to be almost herbaceous with the woody parts of the stems often buried in sand. O. obovatum differs from O. filamentosum by having an abruptly widened corolla-tube and dentate lobes of the upper lip of the corolla.
