Description
|
Herbs, sometimes suffrutescent, rarely clambering, frequently glandular- pubescent or thorny; leaves alternate, stipulate or exstipulate, usually palmately compound, occasionally simple, the leaflets entire or minutely callose-serrulate; inflorescence racemose, terminal or both terminal and lateral, few- to many- flowered, bracteate, rarely ebracteate; calyx deeply 4-parted, persistent or decidu- ous; petals 4, more or less unequal, usually unguiculate; disc usually present, symmetrical or asymmetrical, rarely absent; stamens 6, rarely 4, inserted on a short or more or less elongate androgynophore, occasionally nearly sessile, the fila- *ments more or less unequal and declinate; ovary borne upon a more or less elongate gynophore, rarely nearly sessile, the stigma sessile or stipitate, the ovules numerous; fruit a dry, terete silique, dehiscing from the persistently joined replum by 2 valves; seeds cochleate-reniform, smooth, minutely tuberculate, or transversely rugose.
