Lomaria (Plagioqtria) euphlebia, Kze. 



Caudice crasso lignoso pedali, frondibus in stipitibus elongatis 

 triquetris basi incrassatis 2-3-verrucosis, 1-2-pedalibus usque 

 ad apicem pinnatis subchartaceis olivaceo-fftscis ; sterilibus 

 lato-ovatis lanceolatis, pinnis patentibus 5-6 uncialibus re- 

 motiusculis elongato-lanceolatis sessilibus acuminatis sub- 

 serratis basi eglandulosis, venis subdistantibus furcatis; 

 fertilibus angustioribus magis oblongis, pinnis linearibus 

 elongatis obtusis, involucre dentato-lacerato.

This belongs to an interesting group of Lomaria, which 

 the excellent Mettenius has thought worthy to constitute a 

 distinct Genus to which he has given the name of Plaqio- 

 gyria. My reasons for preserving it in Lomaria are fully 

 given in the third volume of my Species Filicum, v. 3, p. 2. 

 The present one was long known in our Herbaria as the 

 Lomaria triquetra, from Nepal, of Dr. Wallich's Mst. Cata- 

 logue. At length it was figured and described as a Japan 

 Fern by Kunze, above quoted. Drs. Hooker and Thomson 

 met with it, but apparently of rare occurrence, in Khasia, 

 Griffith in Assam, and now recently Mr. Wilford sent home 

 specimens from Tsus-sima : — thus it has a very considerable 

 geographical range.
