suberectis, aciculis parvis intermixtis ; foliolis saepissime 3, raro 5, pinnatis, 
obovato-cuneatis, rigidulis, viridibus, utrinque glabris, praesertim ad apicem 
simpliciter serratis ; rhachi glabra, aciculata, haud glandulosa ; stipulis adnatis, 
apicibus liberis linearibus ; floribus solitariis ; pedunculis brevissimis, nudis ; 
calycis tubo globoso, aciculato ; lobis ovato-lanceolatis, acuminatis, dorso hispidis, 
exterioribus parce compositis ; petalis magnis, rubellis ; sty lis liberis, villosis,

Stem short, erect, much branched ; prickles large, scattered, slender, \ in. long, 
intermixed with small aciculi, but not passing down into them gradually. Leaflets 
usually 3, sessile at the tip of the petiole, rarely 5, pinnate, obovate-cuneate, J in. 
long, rigid, green, glabrous, simply toothed, principally at the tips ; petioles glabrous 
and aciculate, not glandular ; stipules adnate, with linear free tips. Flowers solitary ; 
peduncles very short, naked. Ccdyx-tube globose, very prickly ; lobes ovate-lanceolate, 
with a long point, hispid on the back, the outer slightly compound. Corolla 1^-2 in. 
diam., pink. Styles free, villous, not protruded. Fruit globose, i in. diam., prickly, 
crowned by the erect persistent sepals. 
Rosa stellata was first collected in July 1897 by Mr. E. O. 
Wooton in the Organ Mountains of New Mexico and again in the 
White Mountains of Lincoln County, at an elevation of 5,500 to 6,000 
feet. It has also been found very abundant in the Sacramento 
Mountains at an even greater elevation. This very remarkable and 
distinct species is doubly interesting from the fact that it contributes 
a second Rose to that hitherto monotypic section minutifoliae of 
Crdpin. Its discovery was also one of great interest from a botanico- 
geographical point of view, for here we have two Roses belonging to 
the same section, the one Rosa minutifolia Engelm. of Lower 
California, the other Rosa stellata Wooton of New Mexico, possessing 
in common some very important points of resemblance, growing in 
almost the same latitudes, and yet separated from each other by some 
700 miles of country.
