Discussion | Stem indument of Veronica peregrina has been used to distinguish var. xalapensis with a glandular-hairy stem (F. W. Pennell 1935), a variety that seems to be confined to drier places than the type variety. Variety laurentiana is also differentiated from var. peregrina in having a glandular-hairy stem, fleshier leaves, shorter stamens, smaller corollas, and slightly differently shaped capsules (Frère Marie-Victorin and J. Rousseau 1940). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Synthyris schizantha is known from the southern Olympic Mountains in Grays Harbor County and the Cascade Mountains in Lewis County, Washington, and in the vicinity of Saddle Mountain in Clatsop County, Oregon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
