The Historical USGS Topo Garfield 1976 and Beaver 1976 maps were used to measure 1.0 mile northwest along Hwy 62 from the Carroll County line. A polygon was drawn to encompass the road from approximately 0.8 to 1.2 miles. A marker was placed in the approximate center of the polygon and the U. Radius was then resized to the polygon.
On rocky roadside slope.
Common. S. laciniatum and putative hybrids also here (see 3336B and 3336C).
