Jungermannia filicina was first found b y Dr. Swartz “ in mon- 
tibus altissimis Jamaice,” and described by him in his Florg 
Indie Occidentalis ; but no figure of it having ever appeared, I 
have thought right to subjoin one here ; and I have done so the 
more willingly, since I have been so fortunate as to possess speci- 
mens with the fructification, which Swartz never saw. Its ramifi- 
cation is like that of Sertularia abietina; and when the plant is 
dry, the leaves are not very unlike the teeth of that zoophyte. 
Not only the mode of branching, but the shape of the leaves re- 
move it from the rest of the species of the genus, _ Its nearest 
affinity amas the described ones is perhaps J. dilatata and
