POLYPODIUM (§ Gontoputzsrum) verrucosum, Wall. 
Wart-leaved Polypodium. 
Potypoprum (§ Goniophlebium) verrucoswm ; caudex long, stout, creeping, very 
scaly, stipites one and a half foot or more long, distant, terete ; fronds two 
to three feet long, oblong, acuminate, firm-membranaceous, pinnate ; pinne 
numerous, but distant, six to nine inches long, an inch to an inch and a 
half broad, oblong, costate, articulated upon the rachis, suddenly and 
shortly acuminated, entire, or serrated chiefly at the apex, nearly sessile, 
the base obliquely and obtusely cuneate ; sori copious, in two compact lines 
nearer the costa than the margin, sunk in a very deep cavity or sac, which 
cavities form prominent warts or tubercles on the upper side of the pinne ; 
primary veins horizontally patent, nearly straight, approximate: these are 
united by veins which form the letter V inverted (A); areoles terminating 
in a free clavate veinlet, lowest areole next the costa the largest, and bear- 
ing a free soriferous veinlet, arising from the inferior angle.

Has. Penang and Singapore, Wailich, 1829. Island of Amboyna, De Vriese 
and Teijsmann, 1859-60, n. 54. I also introduce with some doubt x. 51, 
52, and 73 of De Vriese and Teijsmann, from Ceram and Java; and 
Cuming, n. 227, from Luzon.—Imported into Europe by — Rucker, Esq., 
and cultivated at Kew. 
For a long time I had seen no specimens I could decidedly 
refer to this species of Polypodium, save those of Dr. Wallich, 
and, very recently, from Dr. de Vriese and J. E. Teijsmann, from 
Amboina. Mr. Cuming’s n. 291, from the Philippine Islands, 
I suspect is a young state of this plant ; the specimens are very 
conspicuously pubescenti-villous: some of the fronds so young 
that they are strap-shaped, a foot and more long, and quite un- 
divided. With some degree of doubt I bring to this Cuming’s 
n. 227 (Luzon), De Vriese and Teijsmann, n. 51 and 52, from 
Java, and 73, from Ceram; the warts are much less prominent. 
These warts, when perfect, have a depressed disk at the apex, 
looking like an operculum ; and in some very old specimens, 
when the sori have fallen away, there is a circular opening left on 
the pinna. ; 
It is a very handsome, and I believe little-known species, with 
fructifications nearly if not quite as remarkable as those of the 
NOVEMBER Ist, 1861].
