Morphology General Habit
Creeping annuals or perennials
Morphology Leaves
Leaf-blades linear to narrowly lanceolate; ligule a line of hairs
Morphology Reproductive morphology Inflorescences
Inflorescence spike-like, composed of several to many very short racemes ± embedded in a thickened central axis, sometimes shedding single spikelets, more often shedding a segment of the axis with embedded raceme, or even the whole inflorescence; raceme-rhachis mostly triquetrous and prolonged into a subulate tip (but suppressed in S. oostachyum and S. clavigerum), bearing spikelets singly, their lower glume abaxial
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets lanceolate to ovate, plump; lower glume membranous, much shorter than the spikelet; upper glume resembling the lower or almost as long as the spikelet; lower floret ♂ or barren, as long as the spikelet, its lemma and palea (this absent in S. micranthum) chartaceous to coriaceous, smooth, acute; upper lemma similar to the lower but slightly smaller, its margins inrolled and clasping the edges of the palea, but leaving the acute tip of the palea free
Morphology Reproductive morphology Fruits
Caryopsis lanceolate to oblong, plano-convex.
