Hildenbrandia sp._58GWS (A)

This genetic group has only 3 (July 2018) verified records from upper to lower intertidal to habitats from RI, MA and NB. 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.
