The leaves are flat, short, bluish-green, more or less acute, hairless. The sheaths are large, grooved, inflated. The ligules are short. The panicle is rigid, green, inversely lance-shaped, egg-shaped, compact, in two rows, the branches short and rigid, solitary or 2-3, stout, erect to spreading, smooth, more or less in two rows. The spikelets are but shortly stalked, crowded, linear-lance - shaped, 4-10 - flowered. The rachis is angular. The flowering glumes are 3-5, blunt, with a short point. The florets are large.

The habitat of this plant is sandy sea-coasts. The plant has the grass habit. The root is fibrous. The stem is erect, leafy throughout almost, bent below, slender, hairless. The leaves are bristle-like, short. The upper sheaths are large, inflated, the uppermost distant from the spike. The ligule is short and auricled. The panicle is erect, simple, one-sided, close, short, oblong, pale-green, shining. The rachis is smooth. The spikelets have awl-like awns, and are all turned one side, being in fruit wedge-shaped, and the flowers are keeled and flattened. The flower-stalks are short and stout. The rachilla is smooth. The lower empty glume is very small, with awl-like tips, the upper 3-nerved, membranous (hence membranacea). The flowering glumes are distant, very narrow, with prominent nerves, rounded below, flattened above, narrowed to the awl-like awn. The flowers are triandrous. The ovary is hairless. The glumes are very unequal, often only one (hence uniglumis). The plant is 6-12 in. high, flowering in June and July, and is a herbaceous annual.
