The Trees of Wyoming. 105 



(1) WILD PLUM. 



(Prunus Americana Marsh) 



Description. Leaves ovate, pointed, sharply toothed, smooth when old: 

 fruit globose, red or yellowish; seed flattened. 



This small tree occurs with more or less frequency in 

 the northeastern counties and yields occasionally a con- 

 siderable amount of its pleasantly acid fruit. It is well 

 worthy of cultivation for not only does it yield better 

 fruit and more of it, when the tree is cared for, but it is at 

 the same time a desirable addition to the trees of the 

 home grounds, because of its wealth of white flowers. 



(2) WESTERN CHOKE CHERRY. 



(Prunus demissa (Nutt) Walp.) 



Description. Leaves ovate, acute, finely serrate: the white flowers in 

 dense, cylindrical clusters: fruit when ripe nearly black. 



In most localities this is only a small shrub but in 

 very favorable situations it becomes a tree 20 or more feet 

 high. The handsome, clustered flowers and fruit ought to 

 give it more extended use in ornamenting the home 

 grounds. From the fruit may be made a superior jelly, 

 especially when mixed with other native fruits such as the 

 Barberry or Buffalo Berry. 



Apple Family. 



(Pomace ce] 



Of the several genera in this family we need to notice 

 but two. These in common with the others have a fleshy 

 fruit formed by the thickened calyx tube which encloses 

 the seed vessels.
