LOMARIA. WiLi.DKXoAv. 



Fronds simple, pinnatificl or pinnate; the fertile fronds 

 contracted. Sori subniarginal or contracted, linear and indusiate, 

 the indusiuni subintraniarginal. 



The fertile fronds always contracted. 



Moore, Benthani, Swartz, Schkuhr, Mettenius, and others, 

 have considered the British Fern about to be described as a 

 Blcchnum, and the sori when young closely agrees with 

 Blechmim; yet I agree with the Late Sir W. J. Hooker, that 

 the habit and dimorphous fronds are so characteristic of 

 Lomaria, as to make it imperative to place our "Flard Fern" 

 in the genus Lomaria. There is so great an affinity between 

 Blechmim and Lomaria that Sclilechtendal has united the two 

 genera, and his views have been adopted by other able 

 pteridologists. 



Sir W. J. Hooker, in his "Species Filicum," enumerates 

 fifty-five species as Lomaria, and forty as Blcchrmm. 



A large family, but only one species a native of Great 

 Britain.
