Acer rubrum
"Solidago ouachitensis" is likely a relict of times when conditions were colder and wetter. It only occurs in the cooler, moister sites in the Ouachita Mountains, usually in wet forest habitat on north-facing slopes. Associated species include "Magnolia tripetala", "Fagus grandifolia", "Acer rubrum", "Quercus rubra", "Aesculus glabra", "Asarum canadense", "Campanula americana", "Panax quinquefolium", "Toxicodendron radicans", and "Hybanthus concolor".
