1. Rosa stellata Wooton, Bull. Torrey Club 25: 152. 1898. 
Type LocaLiry: Near the Cueva in the Organ Mountains, New Mexico. Type col- 
lected by Wooton (no. 126). 
Rance: Dry slopes, Organ and San Andreas Mountains, New Mexico, in the Upper 
Sonoran Zone. 
The stellate pubescénce of the stems and the lerge rose purple flowers are very 
characteristic. This species is to be expected in some of the drier and hotter moun- 
tains of the southern part of the State or in northern Chihuahua, but as yet it has 
not been found. It lends itself to cultivation tolerably well, though increased moisture 
and a richer soil tend to make it grow slightly taller and cause the flowers to become 
paler. 
2. Rosa mirifica Greene, Leaflets 2: 62. 1910. 
Type Locauity: Near the Mescalero Agency, White Mountains, New Mexico. 
Type collected by Wooton (no. 193). 
RanGE: White and Sacramento mountains of New Mexico, in the Upper Sonoran 
Zone.
