Hildenbrandia sp._40GWS (Ar/A)

This genetic group has 15 (July 2018) verified records from upper intertidal to subtidal (10 m) habitats from MA central Labrador, NL. The genus Hildenbrandia has 36 (and counting) genetic species in the Canadian flora rather than the three or four listed (Gabrielson & Lindstrom; Sears 2002). Considerable taxonomic work remains.
