Notes
| Previously CRPR 4.3; move to CRPR 1B or 4? May be taxonomically distinct or just a phenotypic response to the environment; needs further study. A synonym of Boechera repanda in TJM 2; B. repanda was recently placed into the genus Yosemitea, but varieties were not recognized. See Flora of California 2(2):63 (1936) by W.L. Jepson for original description, Novon 13:388 (2003) for taxonomic treatment, and Systematic Botany 38(1):192-209 (2013) for placement of B. repanda into the genus Yosemitea. |
