Obs. — Consequent on this genus having amorphous sori, it 
has always been placed in the tribe AcrosticliecE ; it, however, 
in habit differs from any other genus in that tribe. Its verna- 
tion is peculiar ; and although the axis of development is not 
very evident, I have, nevertheless, satisfied myself that it is 
articulate, which, with the coriaceous texture and stellated 
pubescence of the fronds, being analogous to Kipliololus ; I 
therefore consider the division Eremobpa the natural place- 
for the tribe Flalycereos.
