Mt. Albert Goldenrod, verge d’or simple à bractées vertes

Solidago chlorolepis Fern. is found only on Mt. Albert and adjacent peaks of the Gaspé Penisula, Québec.  It is the only eastern species that is consistently short (4-22 cm tall) with small involucres (x=4.5 mm; 4-5.6 mm range). The species was treated as Solidago simplex var. chlorolepis (Fern.) Ringius in Semple & Cook (2006 FNA) and was included in ssp. simplex.  Semple & Peirson (2013) supported recognition of the taxon at species level.  It is diploid (2n=18). 

Solidago chlorolepis range Semple draft

Semple et al. (2019) presented a multivariate analysis of all 13 species of S. subsect. Humiles.  In the analysis of the 6 species native to the midwest and northeastern US and adjacent Canada, all specimens of the S. chlorolepis a priori group were placed a posteriori into S. chlorolepis.
