CERTAIN WESTERN ROSES. 263 



lets quite constantly 7, very unequal, all obovate, or the odd 

 one oval, acutely and simply serrate, deep -green and glabrous 

 above, beneath paler and puberulent without glands ; rachis 

 destitute of prickles and with very few small glands, but 

 pubescent; stipules not large, loosely glandular-ciliate: flowers 

 solitary, peduncle short, glabrous ; fruit very large for the 

 group, round-ovoid, retaining to the last its crown of sepals. 

 Yellow pine forests, south of Naylor, Klamath Co., Oregon, 

 22 Sept,, 1902, F. V. Coville. 



Rosa myriadena. Apparently low, the branches not slen- 

 der, rigid, divergent, unarmed except by quite constant, 

 usually paired, infrastipular spines, these long, stout, mani- 

 festly curved: leaflets constantly 5, oval, obtuse or acutish, 

 doubly serrulate, green, glabrous and smooth above, very pale 

 beneath as if glaucous, but this face, under a lens, reticulate- 

 venulose, puberulent, the rather prominent midvein and vein- 

 lets beset with many small subsessile reddish glands; rachis with 

 a few short gland-tipped prickles, also dark with the multitude 

 of red glands ; stipules, as in the group, large, strongly glan- 

 dular not only marginally but superficially on the outside : 

 flowers 1 to 3 terminating the branchlets ; peduncles naked 

 and glabrous; sepals glandular-prickly both marginally and 

 on the outside: young fruits globose. 



Huckleberry Mountain, Jackson Co., Oregon, 2 Aug., 1897, 

 Coville and Applegate; type on U. S. Herb, sheet 380588. 

 No fruits are mature, yet doubtless the calyx leaves are per- 

 sistent. 



Rosa muriculata. Stout, probably tall, the bark green, 

 glabrous, bearing a pair of stout but not long spreading or 

 ascending infrastipular prickles only, the flowering twigs 

 wholly unarmed: leaves rather small, of 5 or 7 leaflets, these 

 broadly ovate, the terminal rather obovate, none acute, the 

 serrature mostly double, both faces almost equally green, the 

 upper glabrous, the lower sparsely muriculate with callous 

 white points which at first bear a small pellucid gland, this
