Notes

Notes: Previously CRPR 1B.1; taxonomic distinctiveness from var. brevipes is uncertain. Originally treated as a Channel Islands endemic, CRPR 1A plant, but plants determined to be var. hassei have recently been found throughout the range of the species; needs further study. Rediscovered on the Palos Verdes Peninsula (LAX Co.) by A. Sanders in 1976, where plants are an extreme variant and only a few remain; the occurrence was diminished by grading in the 1930's. Rediscovered on SCM Is. in 2005, where previously only known from a single wild specimen that died in 1908. The only other wild specimen known from the Channel Islands (SCT Is.) died in 1936. See Pittonia 1:222 (1888) for original description, and Annals of the Missouri Botanical Garden 19:256-257 (1932) for taxonomic treatment.
