Notes: FNA7: "Subspecies glauca, which is the most morphologically variable and most widespread North American taxon in Noccaea, corresponds to Thlaspi montanum var. montanum in the sense of P. K. Holmgren (1971) and R. C. Rollins (1993). As indicated above, that variety is a strictly European taxon."
