Rosa ampufowa. Shrub evidently large, bark of branches 

 a year old dull red-brown, very sparsely armed with a few 

 slender ascending prickles, the flowering twigs of the season 

 with similar very sparse armature, but augmented by 1 to 3 

 infra-stipular spines : leaves very large for the group, of 7 not 

 very unequal leaflets, all thin, rather deep-green above, glau- 

 cous beneath, but the feather- veins neither at all elevated nor 

 whitened, but branching to form a manifest though faint re- 

 ticulation, the pairs quite approximate, the outline oval and 

 oval-elliptic, doubly serrate, the serratures not deep but salient ; 

 rachis unusually naked, the prickles and stalked glands very 

 sparse and small ; stipules small in proportion to the leaves : 

 peduncles short, loosely glandular-hispid : fruit not seen. 



Margin of Fish Lake, in the mountains of Jackson County, 

 southern Oregon, at an altitude of 5,000 ft., collected by E- I- 

 Applegate, 18 June, 1898 ; type on sheet 381523, U. S. Herb. 

 The leaves are so very large, and have so much of the color, 

 texture and pattern of those of /?. acicularis that but for the 

 small solitary flowers this would have passed readily with 

 many for that species. 



Rosa leucopsis. Shrub not small, the bark of growths of 

 two seasons equally pale-green, unarmed except as to the 



W -i-f A 



of 7 leaflets all broad and obtuse, the pairs very unequal, the 

 lowest round-obovate and obtuse or even retuse, of one-third 

 the size of the uppermost pair, these only broadly obovate, all 

 doubly serrate -toothed, deep-green above, pale beneath, some- 

 what reticulate-venulose on both faces, conspicuously so be- j 



neath ; stipules of the breadth, and the glandular margin f 



usual in the group, but their lobes narrow and acute, triangular- 

 lanceolate to broadly subulate ; peduncles very short, less 

 than 1 inch long, naked and glabrous ; fruits ovoid.
