We are indebted for the superb specimens of this truly elegant Fern to our excellent friend 

 C. S. Parker, Esq. of Liverpool, who gathered them in Demerara in 1824. The same plant had 

 been previously found in the neighbouring district of the Essequebo in Dutch Guiana, and we be- 



lieve no where else. 



It certainly bears a very close aifinity with the Schizeea digitata of the East Indies (the Schizaa 

 marginata of Wall. MSS.) : but that has broader, more compressed, almost winged fronds, and 

 the capsules are not intermixed with the curious chaffy hairs which are so conspicuous in this 



species.
