According to MD DNR Mountain Bugbane is an endemic of the central and southern Appalachian Mountains. The few populations of Mountain Bugbane that are found in Maryland are restricted to a small area of rich montane forests in Garrett County.
Mountain Bugbane flowers in August. Mountain Bugbane is very similar to the more common Black Baneberry. Both plants have tall narrow spikes of white flowers. According to Weakley (2015) the two species can be told apart by looking at the petioles of the basal leaves: Mountain Bugbane has a deep broad groove that runs the length of the petiole while the petiole of Black Baneberry has no groove. The other Actaea species White Baneberry has a smaller spike of white flower that is more rounded than long. The mature fruit of White Baneberry is bright white while the fruit of Mountain Bugbane and Black Baneberry are black when mature.
