Obs. — " Somewhat similar in appearance to Ceplialozia divari- 

 eafa (Sm.) but larger. It is at once distinguished from that and 

 every other species of Cephalozia by the forked branching, and the 

 entire absence of the postical branches characteristic of CejjJialozia. 

 From MarsKjjella {Sarcoscj/jj///fs) it differs in wanting the rhizoma- 

 tous base, in the ramification, the deeply cloven leaves and their 

 texture, and (so far as I have seen) in the absence of oil-granules 

 from the cells. As we have only the male plant, wliich has 

 monandrous bracts, its place among other bifid-leaved Juvfjer- 

 mani(B is not easy to assign. Tt is not unHke small forms of 

 /. minuta, Schrad., and /. rif/ida, Lindberg ; but its nearest allies 

 are doubtless /. opacida, n. sp., gathered by myself in the Andes, 

 between Eioamba and the Plateau of Chimborazo, on the rocks 

 shattered by the great earthquake of 1796 ; and /. intricata, 

 Lindenb. et G., found by Liebmann in Mexico, near Oaxaca, where 

 it grew closely interwoven with /. eolorafaT — Dr. Spruce.
