The Apple Family (Malaceae) is represented in the 

 State by three genera containing eleven species, none of which 

 are of any especial importance, but all of which are shrubby 

 plants more or less worth cultivation for decorative purposes. 



The Service Berries (Amelanchier spp.J occur in the 

 mountains mostly in the pine forests, there being 7 species 

 within our limits. These are all good sized shrubs 3 to 6 feet 

 high, with alternate simple mostly coarsely serrate small leaves 

 and rather delicate white flowers in clusters, terminating 

 the branches of the year. The fruits are reddish or dark 

 purplish-black, pulpy, and berry-like. 



There are three Hawthornes (Crataegus spp.j in the 

 State, all of which are large sized shrubs with stout spiny 

 stems and simple toothed or lobed leaves. The flowers are 

 white and borne in clusters much as apple blossoms are, but 

 smaller. The fruits suggest small apples, about ]/ 2 inch in 

 diameter or less. One species is known to the Mexicans as 

 Manzano de puna larga. 



The Mountain Ash (Sorbus scopulina), described 

 originally from Santa Fe Canon, is a shrub from 3 to 

 10 feet high, with compound leaves and small white flowers 

 in large terminal clusters. The leaflets are 1 to l/ 2 inch 

 long. 11 to 15 to the leaf. The fruit is a small berry-like 

 pome. It occurs in the mountains at middle elevations.
