Annual herbs, simple or branched, the branches spreading, 10-35 cm high, bright green; all vegetative parts finely papillate-puberulous or glandular-puberulous, the papillae often clavate, rarely subglabrous. Leaves up to 7 cm long, pinnatipartite with 1-3 pairs of remote, filiform or linear lobes; each leaf subtended by 2 minute subulate-filiform stipules. Racemes several- to many-flowered, lax, becoming very lax in fruit. Sepals 2 • 5-5 • 5 mm long, 0-9-1-5 mm broad, narrowly oblong to oblanceolate-oblong, glandular-puberulous when young; the outer 2 cucullate; the inner 2 saccate and with a broad membranous margin. Petals 4-11 mm long, 2-7 mm broad, obovate or oblong-obovate, rounded, clawed, usually without, but sometimes with a very small appendage or papillose ridge on one side of the claw. Filaments 2-3 ? 5 mm and 2 ? 4-3 • 8 mm long, the 2 short ones mostly with a small append­age, occasionally without. Anthers 0-8-1-8 mm long. Ovary linear; style short; stigma large, capitate; ovules 16-26. Fruits 2-4 cm long, 2-2*8 mm broad, moniliform or sub-moniliform, linear; valves flat, 1-nerved, glabrous or glandular-puberulous, especially when young; style 0-5-1-8 mm long.
