Taxonomic Comments

This record is for L. oreganus in a broad sense, including L. biddlei and Kincaid's lupine. Kartesz (1994, 1999) accepts Lupinus oreganus with two varieties: var. kincaidii and var., oreganus, including L. biddlei in the synonymy of var. oreganus. A phylogenetic study by Severns et al. (2012) indicates that these varieties are best treated as separate species.They explain that L. biddlei was erroneously identified as the nominate species of L. oreganus, so it appears that all material referred to as L. oreganus var. oreganus by Kartesz (1999) is considered L. biddlei. L. oreganus var. kincaidii is re-elevated to species rank as L. oreganus. Sholars and Riggins' treatment in FNA (2023, vol. 11) recognizes the narrow treatment of L. oreganus and include L. biddlei in the synonymy of L. polyphyllus var. prunophilus.
