Plants perennial; clumped, rhizomes woody. Culms 10-60 cm, branched above the base. Leaves mostly basal; auricles absent; ligules of hairs; blades flat, strongly veined, sharply pointed. Inflorescences terminal, usually exceeding the upper leaves, contracted panicles; branches ascend¬ing to erect; disarticulation beneath the caryopses. Spikelets laterally compressed, unawned, with 3-7 bisexual florets, distal florets reduced. Glumes subequal, longer than the adjacent lemmas but exceeded by the distal florets, acuminate; lower glumes 5-7-veined; upper glumes 7-11-veined; calluses hairy; lemmas membranous to papery, 5-7-veined, densely villous on the margins, sometimes also between the veins, unawned to mucronate; paleas equaling or exceed¬ing the lemmas; anthers 3. Caryopses falling free from the lemma and palea. x = 10.
Discussion
Swallenia is a monotypic genus, endemic to California. It is unusual in that only its caryopses break off the plant.
