selected vouchers: WTU
Notes: Circumscription of Lupinus argenteus is challenging, as evidenced by the number of infraspecific taxa that have been described. Until a more contemporary treatment for the Lupinus taxa that occur in WA becomes available the approach taken here is to follow the most recent local treatment (IFBC, 1999).
H&C does not include WA within the range of this taxon, but both Jepson Manual and Illustrated Flora B.C. do.
