Voss's Goldenrod

Solidago vossii Pringle & Laureto was described in 2010 post FNA. It is very rare in wet prairies of two counties northern Michigan.  The species differs from S. houghtonii in having sparsely to regularly finely serrate basal leaves and ray florets 1.2-2 mm wide (Laureto & Pringle 2010; see for illustrations). It is the only octoploid in the genus 2n=72.
