INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Jun 3, 2010
  • location   Pine Flat Reservoir (Fresno County, California, US)
  • family Brassicaceae
  • notes   Habit shot of Streptanthus polygaloides growing on a serpentine substrate of nearly solid rock. Robust plants were branched above, like this one...many others had a single, erect, stalk.

    This species is distinctive in:

    1) Its relatively large, round, wavy-edged, ''clam-shell-like'' upper and lower sepals...which give rise to the epithet ''polygaloides'' (= Polygala-like); and,

    2) It is a remarkable hyperaccumulator of Ni (the chemical element Nickel) which apparently provides defense against herbivory by selected organisms (see this paper for details).
