Streptanthus glandulosus subsp. niger is an endangered subspecies of flowering plant within the family Brassicaceae.[1] Like other genus members, this herb has wavy petal margins with perimeter calluses that discourage larval herbivory.[2] This plant is endemic to the Tiburon Peninsula[3] of Northern California, and occurs at elevations below 150 m on serpentine grasslands.[4] The common name for this subspecies is Tiburon jewelflower[5] or black jewelflower. This annual herb blooms in May and June and displays dark purple sepals. The etymology of this genus scientific name derives from the Greek word streptanthus, meaning twisted flower, with reference to the notable wavy margins of the petals. The subspecies name niger relates to the color of the seeds being black, although an alternate account cites the dark color of the petals as the source of the appellation.
