Leaves paired, 0.5–1 mm long, together continuous around node, membranous. Flowers usually 10–80 per cluster, in 2–5 rows almost encircling node initially, separating as internode expands; basal hairs long, sparse, reddish, mostly in a single row between flowers, not forming a dense protruding cushion; male flowers c. 0.5 mm diam., a few in all rows; female flowers to c. 0.5 mm diam. Fruit less than 2 mm long; seed disc-shaped, c. 1 mm diam. Flowers mostly in spring.
