« Betula alleghanensis Britton, in Britton and Shafer (North Am. Trees, 257, 1908) is maintained by 

 these authors as a species, which is said to have been confused with Betula lenta and Betula lutea. In 

 general appearance it very strongly resembles the latter species, but the scales of its mature fruit are dis- 

 tinctly of a different shape from those of Betula lutea Michaux. For the present the writer prefers to con- 

 sider this tree a form of the latter species.
