Notes:

Vallée des Branloires, Ile de la Possession, Crozet Archipelago, Sample BA038 (coll. date 14/11/1999).Fairly common in dry soil samples, influenced by sea-spray. Rare to almost absent in moss samples and water samples from lakes and rivers.Kerguelen (Le Cohu personal observation).Easily separated from the var. rabenhorstii by its smaller length but almost similar width, and the more rounded and less subrostrate apices. Differs from P. borealis by its larger width. Krammer (2000) argues that P. rabenhorstii and P. borealis can be distinguished based on the valve width.
