Plants perennial; dioecious, staminate and pistillate plants similar; stoloniferous. Culms 10-70 cm. Leaves mostly cauline; ligules membranous, ciliate. Inflorescences terminal panicles, exceeding the upper leaves; branches appressed or ascending, usually spikelet-bearing to the base. Spikelets not disarticulating. Pistillate spikelets with 5-10 florets; lower glumes 1-5-veined, only the midveins conspicuous; upper glumes with 3 conspicuous veins, sometimes with 2-4 inconspicuous lateral-veins; lemmas 3-5 (6) -veined, unawned; paleas shorter than the lemmas, completely surrounding the ovaries, saccate basally, narrowing distally and surrounding the styles, intercostal region coriaceous, veins keeled, scabrous and puberulent, margins scarious. Staminate spikelets with 4-21 florets; lower glumes 1-veined; upper glumes 1-3-veined; lemmas conspicuously 3-veined, unawned; paleas equaling or slightly longer than the lemmas, linear, 2-veined, veins ciliolate. Lodicules 2, cuneate. x = 10.
Discussion
Allolepis is a monotypic North American genus. It used to be included in Distichlis, but it differs in its paleal morphology, in never producing rhizomes, and in its soil preferences.
