Obs. — Fortunately possessing Taylor's original specimens 

 of this species (Interior of New South Wales, Cunningliana, 

 1836 ; Van Diemen's Land, J. D. Hooker, 1820), we have 

 been enabled to arrive at a satisfactory diagnosis. 



From F. congesta, H. f. and T., Falkland Island, it is 

 distinguished by its more regular sub-bipinnate ramification, 

 not irregularly branched, the remarkable areolation of leaf, 

 which Dr. Taylor noted, the basal cells being very large 

 when compared with the other portion of the leaf. In F. 

 congesta the cells are uniform throughout, rather larger than 

 the middle ones of F. diplota. 



The leaves of both F. congesta and F. diplota are more or 

 less apiculate on the young branches, evidently overlooked 

 by Taylor in his description of F. diplota. The same remark 

 is true with F. lohulata. (See Gott. Syn. Hep., p. 445.) 



In Frullania congesta the underleaves are approximate, 

 more obovate, and segments not so acute as in F. diplota.
