BLECHNUM BOREALE. 
Asplenium spicant, and Acrostichum spicant. Spioant is 
its name in the German language, in which it was first 
named in modern times. It is curious that Linnaeus, in 
total neglect of his own characteristics of the two genera 
Osmunda and Blechnum, placed this Fern in the genus 
first-named. This mistake was first pointed out by 
Haller, but it was not until 1793, in the “ Memoirs of 
the Turin Royal Academy of Sciences,” that this Fern 
was correctly placed amoug the Blechnums.
