This is a Hemitelia, according to our views of the Genus, 
but would be an Amphicosmia of the late Mr. Gardner, Lond. 
Journ. of Bot. 1, p. 441 ; differing from Hemitelia in its free 
venation. The Involucre is exactly the same as in our H. Host- 
manni and H, Parkeri, described in the “ Species Filicum,” and 
figured in the 7th volume of our ^‘leones Plantarum.” It is 
probably nearly allied to Cyothca multiflora of Sir J. E. Smith, 
which has the ‘‘ rachis winged,” and which Gardner refers to 
Amphicosmia : but I have never seen an authentic specimen, 
which I believe only exists in the Banksian Herbarium, and 
which is stated to be a native of Jamaica. In general the 
specimens we receive of these gigantic Ferns are too imperfect 
for accurate description, even the stipes is often neglected, 
which not unfrequently affords good characters in the pecu- 
liarities of its clothing especially, as is remarkably the case 
in the species now under consideration ; and, the involucre 
being very fragile, is too frequently injured, and leads one 
astray in regard to the Genus.
