COL. FEILDEN AND MB. GELDART ON SPITSBERGEN PLANTS. 51 
ice-rafts, and other causes, is probable ; but, to my mind, it seems 
indisputable that several plants, now confined to the Polar area, 
must have originated there, and have outlived the period of greatest 
ice-development in that region. To wit, Saxifritga flcvjellaris and 
Pleuwpogun Sabinii, two striking examples of plants only found 
in the extreme northern portions of the globe, and botli circum- 
polar in their distribution. — II. W. Feilden.
