Dryas punctata subsp. hookeriana (Juz.) Jurtz.
Publ. & Syn.Jurtz., J. Bot. Res. Inst. Texas 2: 441 (2008). - Dryas hookeriana Juz., Izv. Glavn. Bot. Sada SSSR 28: 325 (1929). Type (LE): "Rocky Mountains", leg. Hooker, ex Herb. Fischer, Ledebour. - Dryas octopetala subsp. hookeriana (Juz.) Hultén, Acta Univ. Lund., n. s., sect. 2, 42, 1: 1046 (1946).
NotesElven and Murray: Cody (in comment) reported subsp. hookeriana to reach the Arctic in the Yukon Territory. Yurtsev doubted this. We enter it as borderline arctic. Subspecies hookeriana and subsp. alaskensis may belong to a different evolutionary lineage from Dryas punctata s. str., i.e., they may be two races of a Cordilleran and narrowly amphi-Beringian species for which D. hookeriana would be the priority name. There is no combination of "alaskensis" as a race within D. hookeriana.
