Discussion | Subspecies peeblesii is known throughout almost all the southwestern half of Arizona and locally in northwesternmost Sonora, and was recently collected in Grant and Hildago counties in New Mexico. It intergrades with subspp. aurantiaca and rubescens, and hybridizes with all subspecies of Chylismia brevipes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Subspecies aurantiaca is known from Lincoln County, Nevada, south through southeastern California to northeasternmost Baja California, and in Arizona only in westernmost Mohave and Yuma counties. It intergrades extensively with subspp. peirsonii and yumae, and those with white petals (subspp. claviformis, funerea, integrior, and peeblesii); it sometimes hybridizes with Chylismia brevipes subspp. brevipes and pallidula, and with C. munzii. The name Oenothera scapoidea var. aurantiaca S. Watson is superfluous because Watson included O. claviformis Torrey & Frémont as a synonym, which is the basionym of O. scapoidea var. claviformis (Torrey & Frémont) S. Watson. Likewise, Chylismia scapoidea (Torrey & A. Gray) Nuttall ex Raimann var. aurantiaca Davidson & Moxley is also an illegitimate name that pertains here.
