It is not included in the 1911 Report nor in Coulter's Catalogue. Why- 

 should it not receive the same treatment as other escapes? (Toxylon, 

 Populus alba, Ailanthus, etc.) 



Mains ioensis (Wood) Brit. Western Crab Apple. This is a west- 

 ern form, as the range map shows (p. 456). A broad-leaf and a narrow- 

 leaf form are described in the 1911 Report. Both forms occur in White 

 County. Specimens were taken from trees on a low sand ridge about 

 one mile northeast of Reynolds. (See Deam 1911 Report, pp. 248 and 

 250.) 



Amelanchier canadensis (L) Medic. Service-berry, June-berry, May 

 or Sand-cherry. The June-berry remains a small tree in White County 

 and is met with in very sparing numbers in different parts of the 

 county. The specimens taken were somewhat variable, but it is thought 

 all belong to the same species. 



Crataegus crus-galli L. Cockspur Thorn, Newcastle Thorn. A small 

 tree, said to be well distributed in Indiana, but with reports only from 

 the following counties: Decatur (Mrs. C. C. Deam) ; Knox and Gibson 

 (Schneck) ; Owen (Grimes) ; Vigo (Blatchley) ; Crawford, Jackson, 

 Lawrence, Posey and Wells (Deam). More or less abundant along the 

 Tippecanoe and in sparing numbers over the county. 



Crataegus calpodendron (Ehrh) Med. Pear Thorn, Pear or Red 

 Haw. (C. Crus-galli Mill, not L.; C. tomentosa DuRoi, not L.; C. Chap- 

 mani Ashe; etc.). Specimens of this thorn were found in Honey Creek, 

 Monon and Union Townships. It is likely to be found in others. Speci- 

 mens have been examined from the following counties: Putnam 

 (Grimes); Marion, Posey and Wells (Deam). 



The national as well as the State distribution of the thorns must 

 be as yet rather uncertain. For notes on other White County thorns 

 see pp. 445, 446. 



Primus americana Marsh. Wild Red Plum. Found throughout 

 Indiana and reported from thirty-four counties. Single trees and small 

 clumps in various parts of White County. 



Prunus serotina Ehr. Wild (Black) Cherry. Common in all parts 

 of the State. Very common in White County. The wood, bark and 

 fruit are each of some economic importance.
