Bluntleaf yellowcress (Rorippa curvipes) is our most common species of Rorippa, occurring in wet sites throughout the greater Boise Front.  Fruits are lumpy, slightly curved ellipsoids, mostly about 2–4 times as long as wide.  Plants tend to be branched from the base, with stems prostrate to ascending or weakly supported by surrounding vegetation.  Leaf shape is variable, and petals are mostly ca 1-1.5 mm long.
