carpels.—Denver, where in June it is quite common on the plains. 
Licusticum Monranum, Bentham & Hooker. .(Thaspium? montanum, 
Gray.)—1-2° high, often branched ; leaves twice ternately divided; lobes 
linear, linear-lanceolate, or lanceolate, 9-18” long; petioles 1-4’ long, widely 
dilated into a sheath toward the base; fruit variable, oval or broadly oval,

dilated as the marginal; vitte single or double in each interval; involucre 
none; involucels of 5-9 setaceous bracts, which are 2-4” long; flowers 
bright yellow.—Central Colorado, reaching as high as 12,000 feet altitude 
(716, 719, 720, 724), and in Arizona, at Willow Spring, at 7,195 feet
