length of the spine : leaves of a vivid green, wholly glabrous, 

 mostly of 5 leaflets, sometimes 7 ; leaflets mostly elliptic-oval, 

 acutish, simply and sharply serrate; rachis with here and 



as 



stipules remarkably ample for the foliage, the large lobes often 

 equalling and sometimes quite surpassing the area of the body, 

 the whole organ glabrous, glandless, entire: flowers 1, 2 or 3 

 terminating the twigs : fruits subglobose, in maturity retain- 

 ing the calyx upright. 



Mount Eddy, Siskiyon Co., Calif., at 4800 ft., collected 8 

 Sept., 1903, by E. B. Copeland, distributed by C. F. Baker 

 (n. 3875): type in my herbarium, n. 11152. 



Rosa deutescens. Size of the last, the red of the stems 

 and branches obscured by a coat of bluish bloom, the green 

 of the foliage similarly pallid ; armature infrastipular only, as 

 often of a solitary spine as of a pair of them, these both stout 

 and long as well as with downward curv^ature : leaves of 7, 

 rarely 5 or 9 leaflets, these oval, obtuse, somewhat doubly 

 serrate, glabrous above, beneath showing a distinct muricula- 

 tion along the veinlets and elsewhere ; rachis with not a few 

 short prickles and many small not sessile glands ; stipules 

 small and narrow, glandular marginally : mature fruits large, 

 short-ovoid or subglobose, the persistent sepals strongly glan- 

 dular-hispidulous, some longer gland-tipped spines scattered 



over the summit of the fruit. 



Collected only by the writer, on the Siskiyon Mountains, 

 but within the Oregon boundary, 3 Sept., 1889; type speci-

Rosa anacantha. All parts of the shrub, even the most 

 vigorous shoots, unarmed ; bark red or purplish, rendered 

 pale by a coat of bloom while young, older branches devoid of 

 it, and with the bark of the cinnamon roses : leaves of 5 to 7 

 leaflets, the pairs approximate, texture firm, outline oval, 

 margin crenate rather than serrate, both faces pale and dull,
