Glabrous annual with erect or ascending branches, to c. 50 cm or more high; leaves ovate or lanceolate to oblong, 2-5 cm long (incl. petiole), obtuse to emarginate, often mucronate.
Flowers whitish-green, in axillary sessile or stalked globular clusters, or sometimes in short terminal spikes with a few small leaves; bracts and bracteoles narrow, acuminate, shorter than the female perianth; perianth-segments 5, 2-2.5 mm long, broadly spathulate, with long narrow claws so that the ripe fruit is visible between them, and broad scarious mucronate laminas which spread from above the middle; styles 3, thick at the base.
Fruit longitudinally wrinkled so as to appear ribbed, with a thick smooth summit, only the styles usually exceeding the perianth, indehiscent or breaking unevenly.
