 lower lobes ; sori reaching from midrib more than halfway to the edge. — Mett. 

 Fil. Nov. Gran. p. 285. 



Hab. New Granada, Lindujy 293, 1015. — Distinguished by its vestiture and large 

 scarcely-toothed pinnules.

 strong, 4 ft. 1., the base clothed with linear dark-brown scales nearly 1 in. 1. ; 

 fr. 4-5 ft. 1., 2-3 ft. br., with about 20 pairs of pinnce, the lowest 12-18 in. 1., 

 4-G in. br, ; loivcr pinnl. 3 in. 1., \ in. br., with their own breadth between them, 

 the edge only slightly inciso-serrate ; texture subcoriaceous ; rachis and both 

 sides naked ; ivins very distinct, the upper ones of the pinnl. forked, the lower 

 ones subpinnate ; sori reaching from the midrib nearly to the edge. 



Hab. Andes of Ecuador, Spruce, 5343. — This agrees with the preceding in its large 

 Bubentire pinnules, differing in vestiture. 



242. A. (Dipl.) q/athecBfolium, Bory ; caud. erect, subarborescent ; st. firm, 

 erect, dark-brown, nearly naked ; fr. 18-24 in. 1, 12-18 in. br. ; lower pinnos 

 9 in. 1., 3 in. br,, cut down to the rachis in the lower two-thirds into numerous 

 phinl. on each side, the lower ones 1| in. 1., \ in. br., the upper ones inciso- 

 crenate, the lower ones cut down one-third of the distance to the rachis into 

 oblong, falcate, sharply-toothed lobes ; texture herbaceous ; rachis dark-brown, 

 naked, like the stem ; veins pinnate, with 3-4 veinlets on each side in the lower 

 lobes ; sori falling considerably short of the edge. — D. caudatum, J. Sm, fide 

 Mettenius. 



Hab. Luzon, Cmniiuj, 158, and, according to Mettenius, a plant also of Ualan and 

 New Guinea. — A somewhat doubtful species, of which our descrii)tion is taken from 

 Cuming's specimens.

 lanceolate-oblong, 15 in. 1., 9 in. br. ; lower 2n»)il. 4^ in. 1., Ij in. br., stalked,

 J in. br., the lower ones subcordate at the base, tlie upper ones decurrent with a 

 narrow wing ; texture herbaceous, under surface glossy ; veins 4-5 on each side, 

 the lower one branched ; sori copious, reaching from the midrib nearly to the 

 edge.— i^fe«. Aspl. p. 189. 



Hab. Manila, Meyen. — Our single specimen of this is very imperfect, and our descrip- 

 tion is taken in part from Mettenius. The alliance of both this and the preceding is 

 with polypodioides. 



244. A. (Dipl.) polypodioides, Mett. ; ca^ld. erect, subarborescent, densely 

 clothed at the crown with long brown fibrillose scales 1 in. 1. ; st. densely 

 tufted, stout, green, 1 ft. or more 1., ratlier densely muricated, not scaly, but 

 slightly furfuraceous ; fr. 3-4 ft. 1., 1^-2 ft. br., with 8-9 pinnce on eacli side 

 below the simple ones at the apex, the lower ones 4-5 in. apart, 9-12 in. 1., 

 in. br. ; pinnl. numerous, spreading, 2-3 in, 1., ^-| in. br., cut down nearly to 

 the rachis into linear-oblong slightly-toothed lobes ; textm-e herbaceous ; both 

 surfaces naked ; colour briglit-green ; rachis green, stout, nearly naked ; veinlets 

 aliout G on each side in the lobes ; sori falling distinctly short of the edge. —

Hab. Himalayas (up to 8,000 ft.), Ceylon, Malayan Peninsula and Isles. — Our descrip- 

 tion is taken from the plant in cultivation at Kew, no doubt identical with the common 

 Indian and Malayan species thus named, wh\ch la A. frondosum, Wa.\l. An authentic 

 example of I), asperum, Blume, is rather more coriaceous in texture, with lower pinnae 

 15 in. 1. ; even the secondaiy rachises asperous ; the lobes 4 in. 1., with 8-10 veinlets on
