Northern Rough-leaved Goldenrod

Solidago patula Muhl. is distinguished by having finely scabrous leaves and striate-ridged stems.  As treated here it includes only ssp. patula in Flora North America (Semple & Cook 2006 FNA); ssp. strictula is treated now as S. salicina following Semple et al. (2012).  The two species were placed in S. subsect. Patulae Semple & J.B. Beck in S. sect. Argutae by Semple and Beck (2021) based on unpublished DNA sequence data.  The two species were included in a multivariate analysis of S. sect. Argutae by Semple et al. (2021).  This species is diploid throughout its range.
