Information
Caespitose perennial, sometimes short-lived, often spreading by means of stolons; culms 15–60 cm. high. Leaf-blades flat, 2–30 cm. long, 2–5 mm. wide, the margin ± cartilaginous and usually bearing stiff hairs; sheaths of the vegetative shoots often keeled and flabellately interleaved to form compact fascicles. Panicle ± pyramidal, usually spreading, 3–20 cm. long; primary branches in 4–8 whorls, with side branches 3–15 mm. long from the upper 2/3–3/4, sometimes reddish. Spikelets 1.5–2.2 mm. long, smooth or scaberulous, grey-green to pallid, rarely purplish; lower glume oblong, 0.2–0.8 mm. long, 1/4–1/3 as long as the upper, obtuse; upper glume oblong-elliptic, as long as the spikelet; lemma similar to the upper glume; anthers 3, 0.7–1 mm. long. Grain ellipsoid, 0.6–1 mm. long.

Notes
S. ioclados occurs on a variety of inhospitable soil types, and belongs to a cluster of closely allied species. On the one hand it merges indistinctly into S. cordofanus, an annual species favouring overgrazed and weedy sites. On the other hand it grades into S. rangei and S. kentrophyllus, two species which, in general, seem to prefer the more saline or alkaline habitats. A further member of the cluster is S. arabicus Boiss. (1853), a harsh robust perennial from Arabia with rigid glaucous convolute leaf-blades, spikelets 2.2–2.7 mm. long appressed to the primary branches, and having the upper glume shorter than the lemma.
