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.

Remarkable 



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

the total absence of general armature. 



Rosa Helleri. 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 .

 small -flowered group. 



Rosa apiculata. Stems slender but rigid and upright,
