Erigeron vreelandii is similar to E. speciosus in its perennial duration, tall stature, subclasping, spreading leaves nearly even-sized up the stems, corymbiform arrays, and blue rays; it is distinguished by the prominent vestiture of relatively long stipitate-glandular hairs. Intermediates apparently are formed between the two. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron oreganus grows in the Columbia River Gorge, primarily on the north side. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
