Gymnogramme microphylla, Hook . 
Pusilla densissime caespitosa glaberima, caudice gracili subre- 
pente, frondibus triangulari-ovatis membranaceis subdia- 
phanis pinnatis, pinnis profunde bi-tripinnatifidis, laciniis 
ovali-lanceolatis acutiusculis uninerviis monosoratis, stipiti- 
bus gracillimis fusco-purpureis nitidis omnino nudis, soris 
oblongis terminalibus, (nervo ante apicem evanescente). 
Hab. Surureen, Khasiya, Griffith . 
A delicate, quite new Gymnogramme , detected as far as 
we know only by the late Mr. Griffith, in the locality above 
given. It is evidently of the same group of the Genus as G. 
leptophylla , which the late Professor Link formed into a 
separate genus under the name of Anogramme in 1824, and in 
which he has been followed by M. Fee. G . leptophylla had 
already been referred to seven different genera. 
The present plant grows on trees, and forms dense tufts ; its 
short surculose caudices firmly entangled. The stipites are 
extremely slender, filiform, from two to four inches long ; the 
fronds from two to three inches in length, extremely delicate, 
first pinnated, the pinnae . for the most part bipinnatifid, the 
lowest pinnae tripinnatifid, all cut into narrow segments, of 
which the ultimate ones are oblong-lanceolate, rather acute. 
The nerve occupies the centre of these, but disappears before 
the point, and it is the apex of this solitary nerve that bears 
the oblong prominent sorus.
