Douglasia laevigata A. Gray[FNA8, HC, HC2]
smooth Douglasia, cliff dwarf primrose

Publication: Proc. Amer. Acad. Arts. 16: 105. 1880.

Origin: Native

selected vouchers: WTU

Notes: FNA8: "Although the first collection of Douglasia laevigata was from the "Mountains near Mt. Hood," the original description of the species was based on plants collected in the Columbia River gorge, which thus represent the nomenclaturally typical variety (L. Constance 1938), even though that entity constitutes an ecological variant with almost glabrous leaves and loose umbels known only from the gorge. The widespread form, var. ciliolata, has more compact umbels and larger, more toothed, conspicuously ciliolate leaves. Because intermediate forms occur commonly, and even the type specimen of D. laevigata has cilia, the infraspecific taxa are not recognized here."
