CHARACTERS OF TRIBES AND GENERA. 
58.—Lomacramma, J. Sm. (1841). 
Cheilolepton, Fée (1844) ; Neurocallis, Pr. and Moore; Lepto- 
chilus sp., Blume; Acrostichum sp., Hook. Sp. Fil. 
Vernation uniserial, sarmentum scandent. Fronds stipate, 
pinnate, or bipinnate, 2 to 3 feet high, membraneous, 
flaccid. Pinne numerous, lanceolate, 6 to 8 inches long, 
base truncate, sessile, and articulate with the rachis. Veins 
uniform, reticulate; areoles oblong, hexagonoid. Fertile 
segments contracted, wholly sporangiferous, or sometimes 
the contraction only partial, and then the sporangia 
forming a broad marginal line; both states furnished with 
numerous peltate scales.

Oss.— This genus was originally founded on specimens 
of a Fern from the Philippine Islands, which I afterwards 
found had been previously described by Blume under the 
name of Leptochilus lomaroides. In general habit it agrees 
with Cyrtogonium as now restricted, but the numerous and 
curious peltate scales that cover the sporangia marks it as 
a distinct genus; it was originally supposed by me that 
the marginal sori was its normal character, but this is 
now found to be due to the fertile pinne being only par- 
tially contracted. 
* Fronds pinnate.
