This Fern extends throughout Europe, being found in the Scan- 
dinavian kingdoms, in Russia, in Holland, Belgium, France, Great 
Britain, Switzerland, Italy, Germany, Hungary, Croatia, Dalmatia. 
It occurs in North Africa, at Algiers ; and a variety, differing only in 
having a scaly rachis, the 4. squamulosum, of Kaulfuss, is found at 
the Cape of Good Hope and Natal, and in New Zealand. The 
species is recorded as occurring in the Caucasus, and is found among 
the Altaic ranges of Russian Asia, in Soongaria, and in India in 
Kashmir. An allied plant of large size, which we regard as only 
a gigantic variety of this species, has been gathered in Sikkim, by 
Dr. Hooker. The plant seems to be not unfrequent throughout 
North America, extending south to New Orleans and Florida; often, 
however, confused with the sufficiently distinct Lastrea noveboracensis, 
the Nephrodium thelypteroides of Michaux.
