ST CHARACTERS OF TRIBES AND GENERA. 
Oss.—Mr. Moore in his “Index Filicum,” has made 
A. ensiforme a type of a new genus which he names 
Scoliosorus, of which he says, “This plant, having neither 
netted veins nor netted sori, cannot belong to Antrophyum, 
and is quite distinct from every other established genus.” 
This view is consequent on his having derived the cha- 
racter of his genus from Hooker’s figure in the “ Icones 
Plantarum,” tab. 394, in which the sori are shown to be 
interrupted, and with no veins visible. An examination 
of herbarium specimens, however, shows that the fronds 
are traversed by veins which form irregular hexagonoid 
areoles. The sporangia are superficial and only partially 
occupy the venules, forming linear forked generally 
tortuous sori, their incomplete reticulation is not sufficient 
character to warrant the adoption of Scoliosorus as a 
. separate genus.

Gymnogramma sp., Hook. Sp. Fil.; Grammitis, sp.,

Vernation sub-fasciculate, decumbent, rarely short, 
sarmentose. Fronds simple lanceolate, 6 to 18 inches in 
length, coriaceous. Veins internal, obscure, rarely evident, 
uniformly reticulated, forming oblique elongated areoles. 
Receptacles compital, linear, forming oblique, naked sori. -

Grev., Ic. Pl, t. 53; Moore Ind. Fil., p. 51, B. 
Oss.—Hitherto this genus has been placed in alliance - 
with Selliguea, but the vernation of Lozogramma being 
adherent, brings it more in alliance with Antrophyum, — 
from which it differs in the sporangiferous Seege
