A most lovely species of a lovely genus ; our largest specimen, 
from French Guiana, is more than a foot and a half long, and 
nearly as broad at the base. Van den Bosch is of opinion that 
under my 7. anceps I have included other species. The opinion 
of so acute an observer is worthy of every respect, and he may 
be quite right. He has at any rate shown me that I have in 
my ‘Species Filicum’ entirely omitted Kunze's earlier name of 
Tr. Leprieurii ; his plant is ideritical with my South American 
ones, and I gladly preserve that name. i have, indeed, during 
the time that has elapsed since the publication of the first vo- 
lume of ‘Species Filicum,’ received many specimens from diffe- 
rent localities, which I should be disposed to refer here ; but 
the Hymenophyllacee are in better hands than mine at this 
MARCH lst, 1861.
