Solidago Linnaeus. Goldenrod.

Key to Solidago

A genus of 90-110 species, herbs, primarily North American, but with a few species in South America, Macaronesia, and Eurasia. The placement of the "flat-topped goldenrods" has been controversial; they are sometimes excluded from Solidago and treated as an apparently sister lineage and genus, Oligoneuron.

ID notes:Several related genera sometimes mistaken for (and/or sometimes included in) Solidago are included here as keying “fail-safes”. Key adapted (in part) from various sources, especially FNA and SE.
