Lateral nectar glands in pairs, separated or united, sometimes with projec¬tions; middle glands absent or when present rarely joining the laterals. Hairs simple or absent, rarely branched. Stamen filaments with or without appenda¬ges; anthers usually short and obtuse. Stigmas capitate, often shortly bilobed. Siliculae usually with narrowly elliptic septum (angustiseptate), generally compressed contrary to the septum (but sometimes subflattened, or unilocular without septum), dehiscent, sometimes indehiscent and breaking longitudinally into 1-seeded halves.
