Description

Il s'agit de plantes vivaces ou annuelles, parfois suffrutescentes ou stolonifères, généralement rhizomateuses et acaulescentes, aux feuilles basales et rosulées, les caulinaires étant alternes, simples ou disséquées, munies de stipules libres ou plus ou moins adnées au pétiole. Les fleurs, zygomorphes et bisexuées, sont solitaires, souvent dimorphes (présence de fleurs cleistogames). Elles se composent de 5 sépales libres, égaux ou subégaux, souvent auriculés, de 5 pétales libres et inégaux, le pétale antérieur étant souvent plus développé et possédant un éperon, de 5 étamines libres, aux anthèressouvent cohérentes autour de l'ovaire, les 2 antérieures étant munies d'un appendice nectarifère enchassés dans l'éperon corollaire, et d'un ovaire supère à 3 carpelles, aux placentas pariétaux. Les fruits sont des capsules à dehiscence loculicide.
