Discussion | Subspecies 3 (2 in the flora). G. L. Nesom (1993b) merged Solidago californica, S. sparsiflora, and S. velutina without recognizing any infraspecific taxa, as did A. Cronquist (1994). J. C. Semple et al. (1990) compared S. californica and S. sparsiflora to S. nemoralis and found that all three are significantly different in a multivariate analysis. Evidence for separating the two subspecies of S. nemoralis was greater than the support for separating S. californica and S. sparsiflora.
