Frondibus sterilibus hastato-trilobis sen pinnatifidis basi in 
petiolum alatum decurrentibus, lobis oblongis obtuse acu- 
minatis intermedio nunc sinuato subpinnatifidis, fertilibus 
profunde tri-quinquefidis segmentis linearibus acuminatis 
infra lobos non raro sterilibus, stipitibus paleis longis sub- 
ulatis patentibus fuscis squamosis, radice caespitosa.

A plant evidently of the same genus with that figured at 
our Tab. 9 ; and for similar reasons, as in that case, M. F ee 
refers it to Leptochilus. Our plants have a short stout hori- 
zontal very scaly caudex, and the fronds, including the stipes, 
are a foot to a foot and a half long. Strangely enough M. 
Fee quotes J. Smith’s Gymnopteris trilobata under his Hete- 
roneuron diversifolium (Acrostichum Bl. and Cyrtogonium of 
J. Sm.) an extremely different species, and No. 32 of Mr. 
Cuming’s collection. Our species varies with the leaves 
simply oblong and subhastate to pinnatifid with nine and ten 
segments, and with the lower segments auriculate. Gymnop- 
teris tacccefolia, J. Sm. (Cuming, n. 357. Leptochilus, Fee, 
Acrost. t. 50), is closely allied to the more highly developed 
form of this, but it is larger, more membranaceous, decidedly 
pinnate, with the lower pinnae bipartite, and has a creeping 
caudex. Smith’s name is anterior to M. F6e’s, but neither is 
appropriate to so very variable a species.
