Information
Tufted perennial up to 85 cm high, arising from a short oblique rhizome, the stems 1–1.75 mm in diam. at the base; basal sheaths rather broad and papery; leaves mostly basal, the midrib scarcely more prominent than the secondary nerves. Panicle linear, spike-like, (6–)10–21 cm long, the primary branches 1–4 cm long, the spikelets appressed along the whole length of the secondary branchlets, these clustered about the whole length of the primary or the latter naked in the lower 1/3. Spikelets 1.7–2.1(–2.4) mm long; lower glume lanceolate or lanceolate-oblong, 0.8–1.3 mm long; upper glume similar in shape, about 2/3–3/4 the length of the spikelet; lemma narrowly ovate, as long as the spikelet; anthers 3, 1–1.4 mm long. Grain not known.
Range
N1, 2; C1 not known elsewhere.
Altitude range
Grassland and juniper forest on the deeper soils at 1300–1650 m, and coastal plains at 0–50 m.
Distribution
SOMALIA Glover & Gilliland 612; Lavranos 6876; Thulin & Abdi Dahir 6651.
Notes
Gagarariedu, garragarro, saddeho (Som.). Two populations exist in Somalia: one at altitudes of between 1300 and 1650 m in the northern mountains, and another on coastal plains between Hobyo and Ceel Dheere. Apart from the obvious difference in habitat, the coastal population differs in having the narrower leaves with a long tapering point characteristic of S. africanus (Poir.) A. Robyns & Tournay, but it does have the longer upper glume found in the northern population. It is possible that the two populations represent different taxa, but the whole complex, including S. fimbriatus and S. agrostoides, is very poorly understood at present.
