Prunus Mahaleb L. 



State Park, Steuben County. I also found a few specimens in Lagrange 

 County in very sandy soil on the high bank of Pigeon River about 2 miles 

 southeast of Mongo. In cultivation this variety soon forms close colonies, 

 lnd., 111., n. Nebr. to B. C, southw. to Calif., N. Mex., and Tex. 



9. Prunus serotina Ehrh. (Padus virginiana (L.) Mill, of Britton and 

 Brown, Illus. Flora, ed. 2.) Black Cherry. Map 1190. This species will 

 not endure shade. It bears innumerable fruits and the seed germinate 

 readily. The sportsmen favor this tree because its fruit is greedily 

 eaten by birds, while the land owners condemn it because it is difficult to 

 keep fencerows and roadsides free from it. In the primitive forest I think 

 it was infrequent and only locally frequent in its habitat. It was found 

 in beech and sugar maple and basswood and sugar maple habitats, usually 

 associated with black walnut and tulip tree. It was rarely found on black 

 and white oak ridges or in lowland woods. It is now found throughout 

 the state in open woodland and along fences and roadsides. 



N. S. to N. Dak., southw. to Fla. and Ariz. 



10. Prunus Mahaleb L. Mahaleb Cherry. Map 1191. I have found 

 this species as an escape in a few counties and it has been reported from 

 Monroe County. I found several large trees in Clifty Creek Valley in 

 Jefferson County. Miss Edna Banta writes me that it is a more or less 

 frequent tree on the wooded bluffs of the Ohio River from Brooksburg to 

 Madison in Jefferson County.
