Notes

Notes: Recircumscribed as B. rosea ssp. rosea; principal components, cluster, and discriminant analyses clearly demonstrate the existence of two morphologically diagnostic taxonomic groups within B. rosea, but do not support recognition of serpentine endemic and non-serpentine taxa. Violet flowered populations with strongly inrolled staminodes, previously assigned to B. coronaria, are morphologically more similar to B. rosea, thereby greatly increasing its distribution to volcanic, non-serpentine, occurrences in northeastern CA, and north to British Columbia. Treated here as a serpentine ecotype from Interior North Coast and southeastern Klamath Ranges; further genetic and molecular data are needed to assess whether serpentine populations of B. rosea represent a morphologically-cryptic ecotype that is worthy of taxonomic status.
Threats: Threatened by vehicles, dumping, and horticultural collecting.
