This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 Excerpt: ... is common through the northern Rockies as well as the Cascades. 15. Rosa Durandii Crepin This was based on E. Hall 146, which was referred to Rosa kamtschatica by Dr. Gray. Dr. Watson in his monograph reduced it to a synonym of R. Nutkana. Crepin, probably influenced by Watson's treatment, later retracted his species. In my opinion R. Durandii is perfectly distinct from R. Nutkana. The leaves are thicker, more hairy than in that species, and rarely doubletoothed; the prickles are not like those of R. Nutkana, but curved, short, strongly flattened and pubescent. As long as only Hall's specimens were known, the specimens might have been regarded as freaks, but specimens almost exactly like these have since been collected. Oregon: E. Hall 146; Brownville, 1895, Canby; near Springfield, Coville & Applegate 1076. British Columbia. Queen Charlotte's Island, Dawson 8144 (?). Idaho: Lower Priest River, Leiberg 2883. This specimen is very peculiar, nearly unarmed, but with the pubescence of the leaves and twigs of R. Durandii. 16. Rosa Columbiana Rydberg This also is related to R. Nutkana but differs in the strongly curved prickles. It is a rather local plant, the following specimens belonging here: Idaho: Little Potlatch River, 1892, Sandberg, MacDougal & Heller 381; Kooteney County, Sandberg. Oregon: Forest Grove, 1893 and 1894, Lloyd. 17. Rosa Myriadenia Greene This species has the habit, toothing, and glandular pubescence of R. muriculata, but the leaflets are smaller and the prickles are decidedly curved; these characters would place it in the key next to R. columbiana. From this it differs in the smaller and more pubescent leaves. It is known only from the type locality, Huckleberry Mountains, Jackson County, Oregon. 18. Rosa Californica Cham. & S...
