The Shrubs of Wyoming. 23 



An erect, elder-leaved shrub, three to eight feet high, with 

 large showy clusters of red berries in autumn. The leaflets are 

 narrowly oblong, sharply toothed and in four to six pairs. 



This mountain ash is rare in the mountains of this state. It 

 is closely related to the European and the American mountain 

 ash, both of which are often planted for ornament in the East- 

 ern States. 



Western Service-berry or June-berry (Amelanchier alnifolia 

 Nutt.) 



A common shrub among the hills throughout the state. It 

 may be known by its rounded leaves, toothed above the middle, 

 the clusters of white flowers and the purplish, berry-like, edible 

 fruits, which are one-fourth to one-third of an inch in diameter. 



The western service-berry is a very handsome flowering 

 shrub and may well be planted on lawns. Its fruits are sweet 

 and of a pleasant flavor, good to eat from the hand. It is often 

 gathered and used especially for pies. This service-berry is 

 cultivated to some extent both as an ornamental and for its 

 fruits. It has given rise to the cultural varieties, "Alpina," 

 "Gardener," "Williams," and "Greene." It is easily grown, 

 propagating itself readily from seed and is often multiplied 

 from the sprouts which arise about the base of the plants. 



HAW or HAWTHORN. 



(Crataegus). 



The haws are shrubs or small trees, bearing large thorns on 

 the branches and with showy white flowers produced in great 

 abundance. They have small berries borne in clusters and con- 

 taining large bony seeds. There are two species in this state, 

 both of which are desirable ornamentals and well worthy of cul- 

 tivation. Their berries though edible are apparently of no 

 value. 



Black Haw (Crataegus rivularis Nutt.) 



This grows as a large shrub or a small tree with rounded 

 bushy top. Its small leaves are oblong, pointed at both ends
