Hildenbrandia sp._73GWS (Ar)

This genetic group has only 2 (July 2018) verified records from subtidal (2 m) habitat from Makkovic in Labrador, NL, and may have European origins. 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.
