(1) GREEN ASH.* 



(Fraxinus lanceolatus Borkh.) 



Description. Leaflets 5-9, finely toothed on the 

 margins, long pointed, green on both sides: male and 

 female flowers on different trees, in a close cluster, ap- 

 pearing with or before the leaves: fruits about \% inches 

 long. 



This species appears but sparingly in 

 this state, only so far as known on some of 

 the streams in the eastern part, though 

 probably it occurs northward in the lowest 

 portions of the state as well. Its wood is 

 valuable but the trees with us are too small and scatter- 

 ing to have any economic importance except as it may 

 be used as a shade or ornamental tree. 



Plum Family. 



(Drupacece. ) 



This family is represented by the common Wild 

 Plum and one species of Choke Cherry. As is well known 

 these trees are all small, all have a fleshy fruit with a sin- 

 gle stone-like seed. 



PLUM AND CHERRY. 



(Prunus. ) 



Here belong Plums and Cherries of all kinds, too 

 well known to need any description. Our species are as 

 follows: 



*There is a possibility that in the BlaHc Hills of Crook County some specimens of the Red 

 'Ash (Fraxinus Pennsylvania Marsh) may be found. Though it rather closely resembles the 

 Green Ash yet it may be known by the leaves being pale and soft, or velvety, hairy below and the 

 body of the seed being about as long as the wing.
