Rorippa curvisiliqua
Rorippa curvisiliqua is a species of flowering plant in the family Brassicaceae known by the common name curvepod yellowcress.[1] It is native to western North America from Alaska to California to Wyoming.[2] It is also native to the northwest part of Mexico.[2] It can be found in various types of moist and wet habitat, including lakeshores and riverbanks, meadows, roadsides, and mudflats.[3] DescriptionRorippa curvisiliqua is an annual or biennial herb which can be quite variable in appearance. It produces prostrate to erect stems up to half a meter long. The leaves are up to 7 centimeters long and have blades which may be smooth-edged or divided into lobes of varying shapes. The inflorescence is an elongated raceme occupying the top portion of the stem containing many tiny yellow flowers just a few millimeters long. The fruit is a silique which is variable in size and shape but generally contains many minute seeds. This species has been divided into a number of varieties, but some authorities doubt that this division is valid or useful.[3] References
