    Habit
    Creeping annuals or perennials
    Leaves
    Leaf-blades linear to narrowly lanceolate; ligule a line of hairs
    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
    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
    Fruits
    Caryopsis lanceolate to oblong, plano-convex.
