Discussion

Aconitum uncinatum grows in the Appalachian Mountains, on the Piedmont, and on the upper Atlantic Coastal Plain. It is a relatively homogeneous group divided into two intergrading subspecies by J. W. Hardin (1964).

Daughter tubers and connecting rhizomes are seldom present on herbarium specimens because they are easily dislodged during collection.

Available information suggests that Aconitum uncinatum is probably not one of the extremely toxic aconites (D. E. Brink 1982).
