 very acute or commonly short-acuminate at maturity, brownish purple, half 

 grown and unfolded at flowering time; petals elongated, 10-18 mm long; summit

3. A. laevis. 



1. Amelanchier humilis Wieg. Low Shadblow. Map 1098. Known in 

 Indiana as low juneberry. This species grows in colonies in very sandy 

 soil in woods and along fence rows and roadsides. I planted roots of it 

 10 years ago and it has grown well. A few stems have come up from each 

 root, otherwise it has not spread. The large fruit is edible and much 

 relished by birds as is the fruit of all the species of the genus.

la. Amelanchier humilis X laevis. I have this hybrid from Elkhart, 

 Fulton, Lagrange, Lake, La Porte, Porter, Starke, Steuben, and Warren 

 Counties. 



2. Amelanchier canadensis (L.) Medic. Downy Shadblow. Map 1099. 

 Known in Indiana as downy serviceberry or juneberry. This species is 

 more or less infrequent to local throughout the state and is found generally 

 in dry soil on the banks of streams, on wooded slopes, and rarely in level 

 woodland. The stem is usually less than 2 inches in diameter. 



N. S. and e. Maine, and from w. N. E. to Wis., southw. to Ga., La., 

 and Mo. 



2a. Amelanchier canadensis X humilis. I have this hybrid from Cass 

 and De Kalb Counties.

 Brown, Clark, Clay, Crawford, De Kalb, Fulton, Hendricks, Jefferson, La- 

 grange, La Porte, Martin, Morgan, Perry, Porter, St. Joseph, Starke, 

 Steuben, Warren, and Whitley Counties. 



3. Amelanchier laevis Wieg. Allegheny Shadblow. Map 1100. 

 Known in Indiana as smooth serviceberry or juneberry. Frequent to 

 infrequent in the lake area, becoming infrequent to local southward. This 

 species, with the preceding and their hybrids, is frequent on the high 

 dunes facing Lake Michigan. It is also found in old tamarack bogs and
