San Luis Watercress (Rorippa coloradensis)
The San Luis Watercress was described in 1972 on the basis of a herbarium specimen which had been collected in 1875 at some unknown locality in southern Colorado, USA
The species, which is quite conspicuous because of its rather large flowers, probably grew along the margins of lakes and rivers.
The San Luis Watercress is considered extinct.
