General/Distribution: About 7 species, chiefly African and W. Asian; 2 recorded for Pakistan.
Comment/Acknowledgements: It is a new record for our area, whose eastern most limits now extend to Pakistan. It looks very similar to Matthiola but fruits different, with 2 horn-like appendages at the apex of the valves and below the stigma. Some species of Matthiola also have horn-like appendages but from the stigmatic lobes.

Racemes few-flowered, short. Flowers large, handsome, pink or rose; pedicels short, thickened in fruit, suberect. Sepals long, erect, not or slightly saccate at base, with a narrow membranous margin. Petals nearly twice as long as the sepals, obovate-oblong, with long claw. Stamens 6, outer 2 much shorter, filaments linear; anthers long, linear, acute. Lateral nectar glands in pairs; middle glands absent. Ovary oblong, terete, with 2 small processes below the large, emarginate stigma on valves apex, many ovuled; style indistinct, minute.
