Description
Species Description - Dr. Gray's description covers two if not three species. For which of these S. compatus should be used is a matter of question. I have adopted it for the plant of the plains with a dense cyme and usually pinnatifid-dentate stem leaves. Dr. Gray evidently had this plant in mind when he adopted the name coin pactits. The description seems to indicate mostly this species, which also I had in mind when I raised the variety to specific rank and it is this that is described and figured in Britton and Brown's Illustrated Flora. On the other hand if synonomy and the citation of specimens are taken in consideration, the name may have been applied to the next, for the first synonym and the first specimen cited belong to that species.
