Distribution. — Central Kentuckj^ northwestward to central Iowa 

 and soiithwestward to Kansas and east to northwest Tennessee. In 

 Indiana the specimens at hand show it to be confined to the south- 

 western part of the State, although Pepoon' reports a single tree found 

 near Dune Park in Porter County. It is found on sandy roadside cuts, 

 base of sandy wooded slopes, etc., and is a common tree in Sullivan 

 County for miles on the wooded bank of the terrace of the Wabash 

 Eivei-. 



5. Pruiius pennsylvanica Linnaeus filius. Wild Red Cherry. 

 Plate 103. Small trees with smooth cherrj^-like bark, somewhat 

 roughened near the base on old trees; twigs smooth, at least at maturity; 

 leaves oval, oval-lanceolate, or ovate, sometimes slightly falcate, 4-10 

 cm. long, and 1..5-4 cm. wide, rounded or narrowed at the l)ase, long 

 acuminate at the apex, margins finely serrate with glandular incurved 

 teeth, glossy and smooth above, generallj^ smooth beneath, sometimes 

 pubescent along the midrib and veins, petioles generallj' smooth, rarely 

 pubescent; flowers appear with the leaves in Maj^ in umbels of 3-7, or 

 sometimes raceme-like but the I'achis shorter than the pedicels; calyx 

 glabrous, the lobes glabrous within and without, entire and glandless; 

 fruit ripens in August, globose, 6-7 mm. in diameter, red;stone roundish- 

 oval, surface granular. 



Distribution. — Newfoundland and New England to the Rock.y 

 Mountains, south to Colorado and eastward through northern Indiana 

 to Pennsylvania and thence in the mountains to North Carolina. In 

 Indiana it is definitelj'' known to occur only in Lake, Porter, Laporte, 

 St. Joseph and Lagrange Counties. It is frequently found on the black 

 oak ridges about Lake Michigan. All other reports of this species for 

 Indiana should be looked upon with suspicion. The one by Chipman 

 from Kosciusko County maj' be correct. The one by Ridgeway^ 

 for Posey County is undoubtedly an error. No doubt Phinney's-^ 

 record for Central Eastern Indiana (Jay, Delaware, Randolph and 

 Wayne Counties) is an error. 



The range of the species is to the north of our area, and like a few 

 others it is found about the Great Lakes south of its general range. In 

 Ohio it is reported only from Cuyahoga County which borders Lake 

 Erie.
