and are borne singly or a few together on short stalks. 



This little cherry is rare in this state, being known only from 

 one locality, Glenrock, in Converse county, where it was dis- 

 covered last year by Prof. Aven Nelson growing on the sand- 

 stone cliffs near the city. It is common in Nebraska, Kansas 

 and the Dakotas, where it is being brought under cultivation 

 both for its fruits and as an ornamental flowering shrub. Its 

 fruits are of fair size and of good quality though often bitterish. 

 It has of late years attracted much attention as a cherry for this 

 western region. It is easily propagated and fruits the second 

 and third years from seed. Many culturists are now bent on 

 improving this promising cherry. It has given rise to the 

 "Improved Dwarf Rocky Mountain Cherry" which has been in 

 cultivation for a number of years.

 the garden pea and bean, the leguminous forage plants (alfalfa,

A medium-sized shrub with long spikes of violet-purple flow- 

 ers, small two-seeded and elongated leaves composed of 5 to 10 

 pairs of leaflets. It is found along streams in the eastern part
