[Deam recognizes three varieties based upon differences in pubescence. More or less glabrous plants represent the typical variety. These are] infrequent in moist or dry woods and probably found throughout the state. [Variety brachycoma has puberulent stems in which hairs are about 0.5 mm long.] Our only specimen is from a woods about 12 miles northeast of Indianapolis now known as "Woollen's Garden of Birds and Botany."
