13 Amelanchier alabamensis Britton (Britton and Shafer, North Am. Trees, 439, 190S), found at Auburn, 

 Lee County, Ala., appears to be very near the above species and possibly later study may show it to be 

 the same. 



44 Amelanchier canadensis spicata (LaMarck) Sargent, which occurs from New Brunswick to New York 

 and Minnesota and south in the eastern mountains to North Carolina, in its extreme forms appears to be 

 specifically distinct from Amelanchier canadensis (Linnseus) Medicus, but intermediate forms of leaves 

 appear to connect the typical orbicular leaf of the variety with foliage of the latter species. Britton and Sha- 

 fer (North Am. Trees, 439, 1908) consider this plant a species and have taken up for it Amelanchier sanguinea 

 (Pursh) Lindley. 



Amelanchier canadensis obotalis Michaux, is here treated as a form of Amelanchier canadensis (Linnaeus,. 

 Medicus. It occurs from Nova Scotia and New Brunswick to Ontario, and northwestward to the Macken- 

 zie River (latitude 65° north); south, in the Allegheny Mountains, to Virginia, and west to Minnesota 

 and Missouri; eastern Louisiana; North Carina (Coast Region) to Alabama (Mobile Bay). 



« Britton and Shafer (North Am. Trees, 441, 1 90S) took up Amelanchier florida Lindley as applicable to 

 the northwestern form of Serviceberry usually included under Amelanchier alnifolia Nuttall Piper and 

 Beattie (Flor. Northw. Coast, 200, 1915) also took up this name as the only one properly applicable in 

 the region covered by their work.
