the petals fall, broad and abruptly long pointed ; pe- 

 tals white, oblong. Fruit purplish red, scarcely edi- 

 ble, often diseased by the attack of a fungus. There 

 is much confusion as to the correct name for this tree. 

 In Britton's trees it is called A. intermedia Spach; 

 in Gray's Manual, 7th ed., A. canadensis, var. Botry- 

 apium; and Wiegand («wi*r-¥r^T!. 14:150. 1912) 

 calls it A. canadensis, v^-^trd^va^ 



87. Amelanchier canadensis (L.). Medic. [A. laevis 

 Wiegand.] Shad-bush, Service-Berry. 



A shrub or small tree, much like the preceding 

 but distinguished by the leaves being purplish brown 

 until full maturity, and by the much more scanty 

 pubescence on the leaves and inflorescence. By ma- 

 turity the leaves are nearly or quite glabrous, but in 

 youth there are hairs on both surfaces, the difference 

 between our two species in this respect being only a 

 matter of degree. Calyx lobes narrower and more 

 lanceolate than in the above, and the fruit more 

 abundant and of better quality. Dates of flowering: 

 March 8, 1903; March 15, 1908; March 1, 1909; 

 March 23, 1910; March 26, 1912; March 23, 1916. 

 The time of flowering varies considerably in differ- 

 ent plants. In 1916 some were in bloom March 23, 

 others not until April 17th. 



This is a rather common plant of dry woods, hill- 

 sides and creek bluffs and banks, usually a shrub, but 

 reaching at times in the mountains, a height of 45 

 feet and a diameter of 20 inches, even in Chapel Hill
