Cardamine
''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 in diverse habitats worldwide, except the Antarctic. The name ''Cardamine'' is derived from the Greek ''kardaminē'', water cress, from ''kardamon'', pepper grass. 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. 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. Taxonomy The genus ''Cardami ...

Lathraea
''Lathraea'' (toothwort) is a small genus of five to seven species of flowering plants, native to temperate Europe and Asia. They are parasitic plants on the roots of other plants, and are completely lacking chlorophyll. They are classified in the family Orobanchaceae. Etymology The genus name ''Lathraea'' derives from the ancient greek (), meaning "clandestine", which is a reference to the fact that it is inconspicuous until it flowers. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Lathraea'' is the sister genus to '' Rhinanthus'', and then to '' Rhynchocorys''. These three genera share phylogenetic affinities with members of the core Rhinantheae: ''Bartsia'', ''Euphrasia'', '' Tozzia'', ''Hedbergia'', '' Bellardia'', and '' Odontites''. '' Melampyrum'' appears as a more distant relative. Species * Common toothwort ('' Lathraea squamaria'') is parasitic on the roots of hazel and alder, occasionally on beech, i ...

Brassicaceae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important Family (biology), family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in Rosette (botany), rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetable ...
