237 BOTANICAL GAZETTE. 



The western roses and, to some extent, all our roses are in some 

 confusion and what my cursory visit to the Pacific coast may have 

 done to clear them up is offered here. 



Rosa Nutkana, Presl, is common in Oregon and northward, but 

 I nave not met with it in California; it is characterized by very broad 

 and stout stipular and cauline spines, which are particularly abunflant 

 on annual shoots, and by large single flowers and large globose or de- 

 pressed fruit. R. Durandii, Crepm, from Oregon, appears to be a 

 form of this species with glandular calyx tube, which in the sjjecics is 

 glabrous. 



Rosa pisifokmis, Oray, stands next t^ tliis and not to the follow- 

 ing. Like it, it has well developed stipular spines, but tliey are slen- 

 der and more terete; corymbs few flowered, fruit smaller; young 

 shoots mostly densely covered with dark red brown slender s|)ines and 

 spiny bristles, by which the ])lant can be distinguished any time, even 

 without flower or fruit. I found it from British Columbia down to the 

 neighborhood ( f San Francisco and Monterey. 



Rosa Cai.ifornica, Cham. & Schl., a bush often 4-5 feet high, 

 along streams, bears its flowers in large com|)Ound corymbs; its annu- 

 al shoots are glaucous, covered with stout straight or often curved or 

 even hooked glaucous c])ines ; form of fruit varialile, oblong or glo- 

 bose, with a more or less distinct contracted neck. — Common about 

 San Francisco, thence northward to the Klamath River and south- 

 ward to Los Angeles and San Dernardino. 



Rosa GV,\r>jocARPA. Nutt. , in the rich woods of the Oregon 

 Coast Ranges with stems 1^^2-2 inches thick and 8 feet high, other- 

 wise mostly a slender bush ; annual shoots densely covered with glau 

 cous or gray bristly spines ; distinguished from all other roses, I be- 

 lieve, by its naked fruit (globose or elongated, sometimes i)ointed at 

 both ends), from which after flowering the united c-dXyx lobes separate, 

 bearing at their base the stamens. 



Campanula scabrklla, n. sp —Several leafy stems from a stout 

 ro"tstock, a few inches high, i to several-flowered, the whole ])lant 

 canescently-scabrous with very short rough pubescence ; lower tufted 

 leaves spatulate, obtuse, attenuated below, stem leaves sessile, lanceo- 

 late, acutish ; flowers erect, lance-linear lobes of calyx as long as tube; 

 ovate-lanceolate lobes of corolla as long as its tube, scabrous outside ; 

 style shorter than corolla ; capsule erect, oblong, lo-angled, opening 

 near the uj)per edge. 



On bleak rocky ridges of Scott Mountain, west of Mount Shasta, 

 under scattered trees of Pinus albicnulis and /'. Bal/oiin'muj with A- 

 iteinoiic Dnimniondii, Wats.,* Wvoiiica alpiiia, P(ilvi:;onii!/i Dai'i'sicF ^ind

 penetrates 3 to 5inches between the fragments of rock; lower leaves i
