Notes: This taxon is known from southern Oregon and California, but was recently (2020) observed in Pacific County, where it appears to be indistinguishable/intergrading with var. acutalata. . There appears to be consensus among different flora projects that this taxon is not distinct from Abronia umbellata var. acutalata.
