1–3 cm in fruit.

sepals spreading or reflexed, linear-oblanceolate, lateral pair not saccate basally;

petals (spreading), white or pink to deep purple, obovate, orbicular, or spatulate, (margins entire or crisped), claw strongly differentiated from blade (slender, often dilated basally, usually minutely to coarsely papillate or pubescent, rarely nearly smooth, apex rounded);

stamens (strongly exserted, spreading), subequal;

filaments not dilated basally;

anthers linear, (coiled after dehiscence);

nectar glands confluent, subtending bases of stamens, (often 6 teeth alternating with filaments), median glands present.

valves each with prominent midvein throughout;

replum rounded;

septum complete;
