Africa. I know few species of the difficult and variable genus 
Trichomanes which is more readily recognized than this; and I 
cannot but express my surprise that Dr. Greville’s excellent 
figure of it, in the ‘Icones Filicum,’ should be so misunderstood, 
as to induce Pres] first, and others following him, to divide it 
from Z. crispum, and constitute a species, under the name of 
T. accedens, distinct from 7. crispum of Linneus and of Plumier 
(the original authority). It is not to be wondered at, that those 
who separate species upon such slight grounds, should go fur- 
ther, and give rise to the above catalogue of synonyms, which, 
for the greater part at least, possessing as I do authentic spe- 
cimens, I can only regard as one and the same species, un-
