Taxonomy:
Distinguishing features: Similar to P. flabellifera but calyx blades nearly triangular, 5-9 rows of elements in BCs
Farinacci & Howe catalog pages: P. flabellifera borealis *
Morphology: Process triangular with serrated end, described from Greenland. AACs may have extended rim elements but no process (JRY - unpubl obs / see images; also Thomsen & Ostergaard 2014)
Ecology & Biogeography: Only known from the Arctic
