Racemes considerably elongated in fruit. Fruiting pedicels horizontal, divaricate, or divaricate-ascending, slender. Flowers: sepals spreading to reflexed, oblong-linear or linear, lateral pair not saccate basally; petals usually yellow or whitish, rarely white or yellow-orange, obovate, orbicular, oblong, linear, filiform, or oblanceolate, claw distinctly differentiated from blade (claw glabrous or papillose); stamens (exserted), equal; filaments not dilated basally, (often papillose basally); anthers linear, (strongly spirally coiled after dehiscence); lateral nectar glands annular, median present or absent, confluent with lateral ones. Fruits long-stipitate, linear, often torulose, terete or latiseptate; valves each with prominent midvein, glabrous; replum rounded; septum complete; ovules 22-70 per ovary; style obsolete or distinct (to 1.7 mm); stigma capitate, entire.
