•with dense adpi-essed hairs ; veinlets forked in the upper, suhpinnate i" the 

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

 Fil. Nov. Gran. p. 235. 



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

 soaroely-toothed pinnules. 



241. A. (Dipl.) venulosum, Baker ; caud. erect, subarborescent ; st. tufted, 

 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., 

 4-6 in. br. ; lower 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 ; veins 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 

 subentire pinnules, differing in vestiture. 



242. A. (Dipl.) ct/athe(Bfoliiim, Bory ; eaud. erect, subarborescent ; st. firm, 

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

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

 pinnl. on each side, the lower ones IJ 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 ; textu/re 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 



Hab. Luzon, Owmvng, 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.) Ma/enianum, Mett. ; fr. ample, tripinnatiiid ; lower pinnae 

 lanceolate-oblong, 15 in. 1., 9 in. br. ; lower pinnl. ^ in. 1., IJ in. br., stalked, 

 oblong-acuminate,^ cut down below into crenate oblong-obtuse segm., ^ in. 1., 

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

 narrow wing ; tesctv/re herbaceous, under surface glossy ; veins 4-5 on each side, 

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

 edge.— ilfeftf. 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.) polj/podioides, Mett. ; cavd. 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., rather densely muricated, not scaly, but 

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

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

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

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

 surfaces naked ; colov/r bright-green ; rachis green, stout, nearly naked ; veinlet^ 

 about 6 on each side in the lobes : sori falling distinctly short of the edge. — 

 HL Sp. 3. p. 257. 



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, which is A. frondosum, Wall. An authentic 

 example of X>. aspervm, Blume, is rather more coriaceous in texture, with lower pinnse 

 15 in. 1. ; even the seoondaiy raohises asperous ; the lobes \ in. 1., with 8-10 veinlets on
