Discussion
Alnus viridis subsp. crispa grows across much of the continent in the far North; widely disjunct populations occur in the Appalachians in Pennsylvania and on the summit of Roan Mountain on the North Carolina--Tennessee border (R. B. Clarkson 1960; E. T. Wherry 1960).
The Cree used Alnus viridis subsp. crispa medicinally for the astringent qualities of the bark and to treat dropsy (D. E. Moerman 1986).
