Description and Figure of a new FERN from Malacca; by Sir W. J. 
Hooker, D.C.L., F.R.A. and L.S. 
(Tas. XI.) 
Potypopium (Drynaria) LOBBIANUM, Hook. 
Frondibus amplis glabris coriaceis nitidis flabelliformibus e basi repeti- 
tim (4-5-ties) profunde dichotomis, laciniis lineari-lanceolatis acumi- 
natis integerrimis, costa centrali, soris utrinque subuniserialibus, 
stipite elongato fusco nudo. —

This fine species of Fern seems, like the Matonia, to be peculiar to 
the locality just mentioned ; at least I have seen nothing approaching to 
it from elsewhere, nor indeed am I aware that it has been gathered by 
any other collector than Mr. Lobb. At the first aspect, a resemblance 
to two Ferns of the Malayan Peninsula and Archipelago is discovered ; - 
namely, Polypodium (Dipteris) Horsfieldii, Br., and P. Wallichii, Hook. 
et Grev., especially in the flabellate and dichotomous ramification ; to 
P. Wallichii still further in the capsules of the sori being “imbedded 
in a gum-like pulpy substance.” Here however the similarity ceases. 
The venation differs considerably from the two Ferns in question, for 
whereas they have always two stout veins (coste) running up each seg- 
ment or division of the frond (generally meeting and uniting below the 
apex), the secondary veins (very conspicuous) running at right angles 
with them (transversely) across the area between the two costas, and - 
again from the costa nearly to the margin (then uniting) ; the tertiary
