Notes: PLANTS database cites a 1924 volume of Annals of the Missouri Botanical Garden as the source of the occurrence of this taxon in WA. No specimens have been located confirming this, and JPM2 indicates that this taxon occurs only in CA and NV. Until a specimen is located confirming presence in WA, this taxon is considered excluded.
