SolidagoÌýzediaÌý(R.E. Cook & Semple) Semple & J.B. Beck is native to woods and thickets of the southeastern U.S.Ìý Its mid and upper stem leaves are broadly lanceolate to rhombic and the stems are only weakly arching (ÌýasÌýS. caesiaÌývar.Ìýzedia). The species is diploid (2n=18).

Semple et al. (2023) treated the species as separate from S. caesia, but the polygenomic data indicated it may be nested within S. caesia.Ìý Further work is needed to fully sort out relationships inÌýS. sect.ÌýGlomeruliflorae.
