Ovary superior, 2(4?)-carpellate, usually 2-celled by means of a false, but usually complete septum, rarely 1-celled, sessile or rarely stipitate; ovules 1 to numerous, borne on parietal placentas on replum margin at periphery of ovary wall, campylotropous or occasionally anatropous; style 1, elongate, scarcely narrower than ovary; stigma capitate.

Fruit: Capsules divided into 2 cells by the usually thin and membranous septum; elongate (at least 3 times as long as wide) and referred to as a silique; cylindrical; torulous; indehiscent; but breaking up into a series of segments at maturity; the upper part with 2–10 large seeds in 1 rows; separated by spongy transverse partitions; tapering above into a long persistent beak; body of silique 2–4 cm long; the beak 1–2 cm long.
