23. {81.) Prunus serotina. "Wild Cherry." 



Once very common, the wild cherry is now rare in most portions of 

 the Wabash Valley. It is partial to the hilly country back from the 

 river, and it is there that the trees of this species attain the largest size. 

 They were formerly found 100 or more feet high and 3 to 4 feet in di- 

 ameter, and a few may ijerhaps still be found having this stature. I 

 have measured but a single tree of this species, however, the one in 

 question being 7J feet in girth, 31 feet to the first branch, and 94 feet 

 high, being by no means so large as some that might be found. 



Flowers about the middle of April, leafing a little later. 



24. (86.) Pirns angustifolia. Narrow- leaved Crab Apple. 



This species has been found in Wabash County by Dr. J. Schneck 

 (see Cox's Geological Survey of Indiana, 1875, j). 528). It is perhaps not 

 so common as P. coronaria, but blooms at about the same time. Ac- 

 cording to Dr. S. it is " usually taller than P. coronaria.''^ 



25. (87.) Pirns coronaria. Crab Apple. 



Common in rich woods, sometimes forming extensive thickets. I 

 have made no measurements, but would say ihat trees 25 to 30 feet high 

 and nearly a foot in diameter are occasionally found ; trunks 6 to 8 

 inches through, being, however, more common. It blooms in April and 

 May, leafing about the middle of ihe former month. 



26. (94.) Cratwgus coccinea. Scarlet-fruited Thorn. 



"(3pen upland woods; not rare; April, May." (Schneck.) No 

 measurements taken. 



27. (95.) Cratccgus cordafa. Washington Thorn. 



Given in Patterson's catalogue of the plants of Illinois on Dr. 

 Schneck's authority' . 



28. (96.) Cratwgus crus-galli. Cockspur Thorn. 



"Low moist thickets; common; March to May." (Schneck.) No 

 measurements. 



29. (101.) Cratoegus subvillosa. " Red Haw." 



Eiver banks chiefly; common; blossoms in April and May. A spec- 

 imen (cut down) measured 37 feet in height, 2^ feet in circumference. 



30. (102.) Cratwgus tomentosa. Black Thorn. 



"Thickets; rare; March, April." (Schneck.) No measurements; 

 begins to leaf April 23 to 25. (Schneck.)

Found by Dr. S;'hneck, but not recognized by the writer, an^l prob- 

 ably rare.
