Notes: Potentially threated by road construction and maintenance. Possibly threatened by erosion, which might be exacerbated by climate shifts. Often misidentified as var. demissa. Leaf attachment and shape are primary differentiating characters between varieties, but these traits can be variable and substrate might be a better indicator of differentiation; needs further study. See Das Pflanzenreich IV. 251(59): 159 (1913) for original description, and American Journal of Botany 20(8): 518-534 (1933) for taxonomic treatment. |
