Cut-leaf or Sharp-leaved or Atlantic Goldenrod
Solidago arguta Ait. is native in woods of eastern North American. The S. arguta complex was studied by Gary Morton (1973 and other publications). The large basal leaves with tapering bases and mid stem leaves have large sharp serrations. Solidago harrisii was included as a variety in S. arguta by Semple & Cook (2006 FNA), but recent unpublished multivariate work indicates species status is appropriate. The species includes diploids 2n=18 and tetraploids 2n=36.
Three varieties are recognized here, with the typical being northern and the other two being southern in distribution.
