INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Jun 3, 2010
  • location   Pine Flat Reservoir (Fresno County, California, US)
  • family Brassicaceae
  • notes   Habitat shot, showing a large number of Streptanthus polygaloides plants growing on serpentine substrate. This species is distinctive in:

    1) Its relatively large, round, wavy-edged, 'banner-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).
