Cardamine is a large genus of flowering plants in the mustard family, Brassicaceae, known as bittercresses and toothworts. It contains more than 200 species of annuals and perennials. Species in this genus can be found worldwide, except the Antarctic, in diverse habitats. The name Cardamine is derived from the Greek kardamon, cardamom, an unrelated plant in the ginger family, used as a pungent spice in cooking.
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.
The nearly 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.
The genus Cardamine was first formally named in 1753 by Carl Linnaeus in his Species Plantarum. As of January 2019[update], there are 230 accepted species in Kew's Plants of the World Online database. An additional 31 new species found in New Zealand were described in 2017 but are not listed in the Plants of the World Online as of January 2019[update].
