Abstract
Three taxa of theSolidago canadensis L. complex are recognized for the Great Plains region:S. canadensis L. var.scabra Torr. & Gray,S. canadensis L. var.gilvocanescens Rydb., andS. canadensis L. var.hargeri Fern. Confusion has resulted from the use of var.gilvocanescens for two different plants: a shortleaved prairie ecotype most closely related to var.scabra and a short-haired form ofS. canadensis var.hargeri. The name rightly belongs to the former.
