Rorippa Backeri
''Rorippa'' is a globally distributed genus in the family Brassicaceae, with species occurring on all continents except for Antarctica. ''Rorippa'' species are natively distributed in the Northern Hemisphere through Eurasia and North America, and dispersed into the Southern Hemisphere through long-distance dispersal. ''Rorippa'' species are annual to perennial herbs, usually with yellow flowers and a peppery flavour. They are known commonly as yellowcresses. Description As a close relative of ''Arabidopsis'', ''Rorippa'' has emerged as a group of valuable model organisms for investigating various biological processes. Researchers have utilized ''Rorippa'' to study developmental phenomena such as heterophylly, weediness, and vegetative regeneration. For example, heterophylly is the ability of plants to produce different leaf forms in response to contrasting environments, such as aerial or submerged conditions. This may incur anatomical or physiological changes and facilitate adap ...

Rorippa Columbiae
''Rorippa columbiae'' is a species of flowering plant in the family Brassicaceae known by the common names Columbian yellowcress and Columbia yellow cress. Distribution It is native to the western United States from central Washington to northeastern California, where it grows in moist to wet, sandy habitat types, such as playas (dry lakes). It is not a common plant; it is known from about fifteen occurrences in the Modoc Plateau region of California, it is a candidate for protection in Oregon, and it is state-listed as a threatened species in Washington. Description ''Rorippa columbia'' is a perennial herb growing prostrate to erect, its densely hairy stems reaching 10 to 40 centimeters in maximum length. The leaves are deeply lobed, the lobes sometimes cut all the way to the midrib. Lower leaves are borne on petioles; upper leaves have bases that clasp the stem. The mustardlike flowers have small yellow petals. The fruit is a plump, hairy silique A silique or siliq ...
