Threenerve Goldenrod (Solidago velutina DC.)

Both POWO and BONAP have merged Solidago californica Nutt. into this species, but they disagree as to the details of the merge. BONAP merged most into ssp. californica, except var. nevadensis, which was merged into ssp. velutina. However, POWO, which recognizes 3 subspecies instead of BONAP's 2, instead merged that variety into ssp. sparsiflora, the subspecies not recognized by BONAP. This does not affect our species-level information but take note that information about subspecies may be inconsistent across different sources using the different treatments.
