Discussion | Staphylea bolanderi occurs in the foothills and at the lower elevations of the Cascades and Klamath ranges, the Sierra Nevada, and the Tehachapi Mountains. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Species 10 (2 in the flora). Staphylea species are cultivated as garden ornamentals. The two North American species of Staphylea differ in their floral biology: the flowers of S. trifolia are pinkish green (sepals) and campanulate with barely exserted stamens and styles; those of S. bolanderi are white and more tubular (cylindro-campanulate) with well-exserted stamens and styles. These differences appear to correlate with pollinators available in the eastern deciduous forest and in California, respectively.
