Whorled Wood Aster, aster acuminé
Oclemena acuminata (Michx.) Greene is native to Cool, mesic to humid forests with usually well-drained, often acidic soils of Appalachian eastern North America from Ontario and Newfoundland south to Tennessee (Brouillet 2006 FNA). The species has oblancelate sharply toothed acuminate leaves often clustered ("whorled") in the upper half of the stem. The species is diploid (2n=18). Brouillet (2006 FNA) summarized the biology of the species.
