Hildenbrandia sp._42GWS (A)

This genetic group has 11 (July 2018) verified records from intertidal to subtidal (4 m) habitats from ME to Cape Breton, NS. 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.
