oblong, falcate, sharply-toothed lobes ; t e x t u r e herbaceous ; rachis dark-brown,
naked, like the stem ; v e i n s pinnate, with 3-4 veinlets on each side in the lower

Hab. Luzon, Cuming, 158, and, according to Mettenius, a plant also of Ualan and
New Guinea.—A somewhat doubtful species, of which our description is taken from
Cuming’s specimens,
243. A. (Dipl.) Meyenianum, Mett. ; f r . ample, tripinnatifid ; lower pinnæ
lanceolate-oblong, IS in. 1., 9 in. br. ; lower pinnl. 4 J in. 1., I J in. br., stalked,

narrow wing ; texture herbaceous, under surface glossy ; veins 4-5 on each side,
tlie lower one branched ; sori copious, reaching from the midrib nearly to the
edge.—Mett. Aspl. p . 189.
Hab. Manila, Meyen.—Our single specimen of this is very imperfect, and our description
is taken in part from Mettenius. The alliance of both this and the preceding is

Hab. Himalayas (up to 8,000 ft.), Ceylon, Malayan Peninsula and Isles.—Our description
is taken from the plant in cultivation at Kew, no doubt identical with the common
Indian and Malayan species thus named, which is A. frondosum, Wall. An authentic
example of D. asperum, Blume, is rather more coriaceous in texture, with lower pinnæ
15 in. 1. ; even the secondary rachises asperous ; the lobes J in. 1., with 8-10 veinlets on
each side. D. ebenum, J . Sm., from the Philippines (Cuming, 1 59), has a slender naked
ebeneous rachis and erecto-patent lobes, with only 4 distant veinlets in each ; and we
have closely allied plants from Queensland, Fiji, and the Seychelles, whioh need further
investigation.

lobes erecto-patent, J in. deep, J in. br., deeply toothed, not contiguous ; rachis
smooth, fiexuose, siibstramineous ; texture subcoriaceous, both surfaces naked ;
veins about 6 on a side in each lobe, with an oblong sorus on each, wdiich is
less th an 1 lin. 1., touches the costa and scarcely reaches halfway to the edge.

Hab. N. India to Ceylon.—A common Indian plant, like A. sylvaticum in texture, a
single lower pinna of this resembling a whole frond of that. We cannot iu any way distinguish
the New Caledonian A. sororium, Mett., of which the trunk is not known, from
the less deeply lobed form of this, and have what appears to be the same from the Society
Islands.
