A. Eastwoop (Botan. Gazette, 33, 1902, p. 148) records the plant under the name 
P. macrocarpa R. Br. and gives as type locality "Melville island”; this is evidently an error

Gmelin“. 
In Melville island P. macrocarpa does not occur, nor has it been recorded by R. BRown 
who described P. arctica from this island.

also on the upper side (f. hrsuta N. Hartz, Medd. Grönland, 18, 1895, 
p. 319).
