Type in Herb. Gray. 



The two species just described, scopariadi\\6.hcviiptcrocarpa, 

 are much alike; heviiptcrocarpa is a taller and stouter plant, 

 its racemes are longer, its capsules somcAvhat larger with a 

 large, well developed half-wing which is very small in the other 

 plant; the two plants, however, have nearly the same range, 

 and it is not easy to resist the impression that, in treating of 

 the two, we are dealing with but one species.
