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.

Represented by 17 genera and 42 species in the present area.

16 (15) Stamen filaments not appendaged; siliculae often elongated with entire margin or wings   Thlaspi
+ Filaments of the longer four stamens generally appendaged (not in our single species); siliculae ± suborbicular with denticulate margin or wing (in our species)   Aethionema
