Herbs, annual, gynodioecious, 2.5–11 dm. Stems erect, usually simple, sometimes branched distally, glabrous or minutely pubescent. Leaves fugaceous; ocrea margins ciliate; blade linear, larger ones falcate, (3–) 11–33 (–51) × 0.3–1.3 (–3) mm, base barely tapered, margins not hyaline, apex acuminate, glabrous. Inflorescences (10–) 20–35 (–45) mm; ocreola encircling rachis, only the base adnate to rachis, apex acuminate. Pedicels spreading to slightly reflexed in anthesis, sharply reflexed in fruit, 0.3–1.1 mm, as long or much longer than subtending ocreola. Flowers bisexual or pistillate; outer tepals appressed in anthesis and fruit, white, distal portion of midrib often inconspicuously greenish, narrowly oblong, 0.9–1.5 mm in anthesis, margins entire; inner tepals appressed in anthesis and fruit, white, narrowly oblong, 0.8–1.5 mm in anthesis, margins entire; filaments dimorphic; anthers deep red; styles and stigmas ca. 0.1 mm in anthesis. Achenes exserted, reddish-brown to yellowbrown, 3-gonous, 1.7–3.4 × 0.6–0.9 mm, shiny, smooth. 2n = 22.
