ortis, margine cartilaginea, venula intramarginale longitudinale nulla;

tenuem cartilagineum liberis, ubique fertilibus. 
Sarawak, Bidi, on river bank, leg. C. J. Brooks. 
Distinguishable from its several Malayan relatives by the venation, but with 
other differences from any single species hitherto known. 
Syngramma Hookeri C. Chr. (Hemionitis lanceolata Hook). 
Sarawak, in a ravine near the summit of Mount Poe, alt. 1,300 m, Foxworthy 
227. 
Already known from New Guinea and Fiji. 
Taenitis drymoglossoides Copel. spec. nova. (Plate VIII.) 
Ehizomate omnino Taenitidis typicale : stipitibus seriatis proximis, 
8-12 mm altis, inarticulatis, deorsum rubidis, sursurn rufo-stramineis, 
glabris : fronde dura, coriacea, glaberrima, supra atroviride nitida, infra 
olivacea, simplice, integra, elliptico-oblonga vel lineari-oblonga, costa 
mediam in frondem latam, supra mediam frondem angustam dissipata ; 
soro inter costam marginemque super apicem costam transeunte con- 
tinuo, leviter immerso.

By the usual definition this would be a Drymoglossum , but that genus properly 
construed is a near relative of Gyclophorus, but by no means near to Taenitis. 
D. rigidum, which I know only by description and figures is apparently near this 
species and also to be transferred to Taenitis: its fronds are more dimorphous 
and the sori deeply immersed. If these ferns are derived from any Polypodieae 
it is from Loxogramme, not from Drymoglossum.
