Cauline leaves (rarely absent), usually petiolate, sometimes sessile; blade (simple or compound), base auriculate or not, margins entire or dentate to pinnately lobed.

Flowers actinomorphic; sepals erect to spreading or ascending, lateral pair seldom saccate basally; petals white, yellow, pink, lilac, or purple, claw usually present, rarely absent, often distinct; filaments unappendaged, not winged; pollen 3-colpate. Fruits silicles or siliques, dehiscent, unsegmented, terete, 4-angled, or latiseptate, rarely angustiseptate; ovules 4–300[–numerous] per ovary; style distinct or obsolete (absent in Subularia); stigma usually entire. Seeds biseriate or uniseriate; cotyledons usually accumbent, sometimes incumbent.
Genera 12, species ca. 335 (10 genera, 85 species in the flora).
The assignment of Subularia to Cardamineae is provisional and based solely on morphology.
