-->{{Treatment/Body |distribution=Maine;Colo.;N.Mex.;Tex.;Utah;Calif.;Kans.;Ariz.;Okla. |discussion=<p>Lycurus is a genus of three species of open rocky slopes and mesas. It is native to two disjunct regions, one extending from Colorado and southern Utah to southern Mexico and Guatemala, the other from Colombia through western South America to west-central Argentina. Two species are native to the Flora region. They can only be reliably distinguished by their vegetative characters.</p> |tables= |references={{Treatment/Reference |id=reeder1985a |text=Reeder, C.G. 1985.
