 described by Muhlenberg from specimens from Lancaster, Pa. I am not 

 well enough acquainted with its variability and its geographical distri- 

 bution. Andersson, in 1867, proposed two subspecies S. rigida and S. 

 angustata which he reduced to varieties in 1868. S. rigida Muhlenberg 

 is referred by Ball in his list as a mere synonym to S. cordata, and S. 

 viyricoides Muhlenberg in Neue Schr. Ges. Naturf. Fr. Berlin, iv. 235, t.
