Description

The leaves can have different forms, from minute to medium in size. They can be simple, pinnate or bipinnate. They are basal and cauline (growing on the upper part of the stem), with narrow tips. They are rosulate (forming a rosette). The blade margins can be entire, serrate or dentate. The stem internodes lack firmness.^{[clarification needed]}

The radially symmetrical flowers grow in a racemose many-flowered inflorescence or in corymbs. The white, pink or purple flowers are minute to medium-sized. The petals are longer than the sepals. The fertile flowers are hermaphroditic.^{[citation needed]}

Taxonomy

The genus Cardamine was first formally named in 1753 by Carl Linnaeus in his Species Plantarum.^[3] As of August 2024^[update], there are 264 accepted species in Kew's Plants of the World Online database.^[1]

The genus name Dentaria is a commonly used synonym for some species of Cardamine.
