TAB. XXVIII. 
Asplenium Griffitiiianum, Hook. 
Casspitosum subcoriaceum minute deciduo-squamulosum, 
frondibus lanceolatis breviter acuminatis basi longe in stipi- 
tem perbrevem attenuatis serratis acumine integerrimo, 
soris totam fere paginam occupantibus, venis obscuris re- 
motiusculis. 
Hab. Mishmee, E. Indies, W. Griffith , Esq. 
In tbe general form of the frond, in colour, texture, in the 
acuminated point, and in the attenuated base, this has a very 
close affinity with our Asplenium, Simonsianum : it differs, 
however, in the shorter fronds, in the serrated margins, and 
in the more remote and more patent lines of fructifications. 
If, however, the frond be held up between the eye and the 
light, the nerves will be found to be all free, each of them 
terminating a little below the apex of a serrature, whereas in 
A. Simonsianum , they unite so as to form an intramarginal 
nerve, characteristic of the Genus Neottopteris , J. Sm: — 
Thamnopteris, of Presl.
