CERTAIN WESTERN ROSES. 259 



presence here and there, at the base of a stipule, of two small 

 straight spines : leaves very large for the group, of commonly 

 5, as often 7 leaflets, these very thin, glabrous, pale glaucous 

 green above and almost white beneath, here with rather ele- 

 vated white feather- veins but no reticulation, the outline 

 obovate or oval, not deeply yet somewhat doubly serrate- 

 toothed ; rachis slender, white, beset with here and there a 

 small spine and more freely stipitate-glandular ; stipules not 

 very broad below, but the large triangular lobes of an area 

 often equalling or exceeding that of the body : peduncles 

 rather long, minutely but not sparsely glandular -hispid ; fruit 

 round-pyriform, orange-colored. 



Sage plains of southeastern Oregon, in L,ake County, col- 

 lected 29 Sept., 1896, by H. E. Brown ; type on U. S. Herb. 

 sheet 283078, the collector's number being 99. Remarkable 

 for the whitish pallor of both stems and foliage, as well as for 

 the total absence of general armature. 



Rosa. Heli-ERI. Shrub stoutish, evidently tall, the dark 

 red-brown bark softly prickly, the slender armature ascending : 

 leaves rather ample yet compact, the commonly 9 leaflets 

 approximate, even occasionally overlapping, of a pale glaucous- 

 green, of oval to oval-elliptic outline, simply serrate toward 

 the base, otherwise doubly so, both faces glabrous, neither 

 one any more than very faintly reticulate ; stipules large and 

 broad ; peduncles 1 inch long, shortly but rather densely 

 glandular-hispid . 



About Lake Waha, Nez Perces Co., Idaho, A. A. Heller, 

 25 June, 1896; type on U. S. Herb, sheet 267361. By the 

 aspect of its foliage, with long pale almost crowded leaflets, 

 this shrub at first glance seems more like the eastern so-called 

 R. blanda than like R. ^ymnocarpa, and only a careful inspec- 

 tion with a lens brings the assurance that it is of this western 

 small-flowered group. 



Rosa apicui,ata. Stems slender but rigid and upright, 

 armed not sparsely with prickles partly long, stiff and ascend-
