Proposal to conserve the name Rosa bridgesii against R. yainacensis, R. calvaria, R. covillei, R. crenulata, and R. myriadenia (Rosaceae)
(2007)  Page(s) 962-964.  
 
Ed. note: Barbara Ertter explains why the name Rosa bridgesii Crépin ex Rydberg should be "conserved" (a technical term meaning allowed as an exception to the rules of taxonomic nomenclature).

@ p. 964: As currently understood (Ertter in Fl. N. Amer. 9, in press), there is a relatively well-defined dwarf rose characteristic of mid-montane forests of the western Sierra Nevada and Cascade Range of California and southern Oregon that includes not only Bridges 62 but also with certainty the types of R. calvaria, R. crenulata, R. dudleyi, R. lesterae Eastw. (in Leafl. W. Bot. 3: 262. 1943), R. gymnocarpa var. pubescens, and R. spithamea var. inermis Engelm. (in Bot. Gaz. 6: 236. 1881), probably that of R. spithamea var. solitaria L.F. Hend. (in Rhodora 33: 204. 1931), and possibly those of R. covillei, R. myriadenia, R. oligocarpa Rydb. (l.c.: 532. 1918), and R. yainacensis.
