Solidago arguta Ait. is native in woods of the eastern US and adjacent Ontario in Canada. It is the northernmost species in S. ²õ±ð³¦³Ù.ÌýArgutae sensu Semple and Beck (2021) that here includes S. boottii,ÌýS. faucibus,ÌýS. harrisii,ÌýS. ludoviciana,ÌýS. tarda, and S. vaseyi. 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 boottii,ÌýS. harrisii, and S. vaseyi (²õ²â²Ô´Ç²Ô²â³¾²â:ÌýS. arguta var. caroliniana) were included as a varieties in S. argutaÌý²ú²âÌý.  All these species were included in a multivariate study of ³§.Ìý²õ±ð³¦³Ù.Ìý´¡°ù²µ³Ü³Ù²¹±ðÌýwhich found support for treating each at the species level (Semple et al. 2021).  Solidago arguta in the narrow sense (i.e., just var. arguta) includes only diploids (2n=18) throughout its range. Semple and Morton (2024) presented a map of the cytogeography of S. arguta.
