NEW WESTERN SPECIES OF ROSA. 11 
stipules, rachis and lower face of leaflets; stipules short, 
ample for the size of the leaves, and plane, obtusish or short- 
pointed ; leaflets mostly 9 or 11, somewhat cuneate-obovate, 
obtuse, sharply serrate from the middle, otherwise entire: 
flowers solitary and short-peduncled, small, rather pale; 
sepals broad, woolly-ciliate, bearing very short and incon- 
spicuous foliaceous tips : fruits large for the plant, depressed- 
globose, of a light red (between scarlet and orange). 
This rather common rose of the middle and northern 
Rocky Mountains has often been taken for a stunted and 
subalpine R. blanda, though it is more commonly labelled 
in the herbaria as R. Woodsii ; but to this latter it bears no 
intimate relationship at all; for that is a shrub with per- 
fectly straight prickles, glandular-edged very narrow and 
acute stipules, ovate fruit and shining foliage. 
My best herbarium specimens are those collected by Mr- 
John Macoun in Assiniboia (Canad. Surv. numbers 10532 
and 10533), and by myself near Cheyenne, Wyoming. It 
belongs to the region of dry elevated plains, and is subal- 
pine as to elevation. 
R. manca. Dwarf subalpine shrub, sometimes a foot high 
or more, rather freely branching, the glabrous and smooth 
red stem and branches armed with few and stoutish com- 
pressed and very strongly recurved prickles: leaves small, 
the leaflets about 7, from somewhat obovate to elliptic, thin, 
sharply but not deeply serrate, the serratures callous-tipped 
_and the larger with one secondary tooth, all smooth and 
glabrous on both faces; stipules extremely narrow, glandu- 
lar, the long and narrow though prominent auricles more 
herbaceous: flowers solitary at the ends of short leafy branch- 
lets: receptacle and back of sepals glabrous and glaucescent; 
sepals finely woolly-margined and with notable scattered ses- 
sile black glands among the wool, usually also appendaged on 
one side by a pair of long spreading linear lobes, the foliaceous 
tips narrowly oblong, entire, glabrous and glandless: corollas 
small: fruit not seen.
