halfway down into acute subfalcate lobes ; texture subcoriaceous ; rachis and 

 under surface finely pubescent ; veinlets 10-12 on a side ; sori subterminal. 

 A. multilineatum, Mett. Fil. Ind.p. 232. (non Wall.) 



Hab. Ceylon, Malaya, Fiji. Much larger and less hairy than the last, with more 

 numerous veins, and a very fugacious involucre. 



173. N. multijugum, Baker ; st. 1-2 ft. 1., strong, erect, subglabrous ; fr. 3-4 

 ft. 1., 12-15 in. br. ; pinnae 6-8 in. 1., f-f in. br. ; cut two-thirds of the way down 

 to the raclris into close, acute, subfalcate lobes \ in. br. ; texture subcoriaceous ; 

 rachis and both sides nearly naked ; veinlets 10-12 on a side ; sori near the 

 midrib. Aspidium, Wallich. 



Hab. Malayan Peninsula. This comes very near the last, but is nearly naked and 

 more deeply cut, with the sori in a different position. 



174. N. hirsutum, J. Sm. ; st. 1 ft. or more 1., grey, villose ; fr. 3-4 ft. 1., 

 1^ ft. br. ; pinnae very close and numerous, spreading, the largest 10 in. 1., 

 f in. br. ; cut down halfway to the rachis into entire, linear-oblong, subfalcate 

 lobes ; the lower ones with a gland beneath at the base ; texture subcoriaceous ; 

 rachis densely clothed with soft spreading hairs ; under surface glandular ; 

 veins 6-8 on each side ; sori medial. Hk. /Sp. 4. p. 70. t. 240. B. {not Don). 



Hab. Philippines, Cuming, 82. Habit of the two last, but the veins much fewer, sori 

 medial, and lower pinnae with a large gland at the base. 



Q 175. N. aridum, Baker ; st. 1 ft. or more 1., erect, naked ; /r.3-4 ft. 1., 12-18 in. 

 br. ; pinnce 6-9 in. 1., f-1 in. br., cut about one-third of the way down into sub- 

 triangular sharp-pointed lobes ; texture coriaceous ; rachis and lower surface 

 naked or slightly hairy ; veinlets 8-10 on a side ; sori in rows about midway 

 between the midrib and edge ; caps, naked. Aspid. Don Prod. Fl. Nep. p. 4. 

 A. venulosum, Wall. A. obscurum, Bl. 



Hab. N. India, Philippines, Malayan Peninsula. This difiers from the three preceding 

 by the under side being nearly or quite naked, and in the position of the sori. A. callosum, 

 Blume, quite agrees with this, except that there is a large prickle.-like gland at the base 

 of the pinnae, and sometimes also of the veins. 



176. N. venulosum, Hk. ; st. 1J ft. 1., naked, greyish, sharply angled ; fr. 

 4 ft. 1., 12-18 in. br. ; pinna numerous, the lowest short and very distant, the 

 largest 8-9 in. 1., 1 in. br., cut down halfway to the rachis into slightly-toothed 

 oblong lobes ; texture subcoriaceous ; both surfaces naked ; colour bright-green ; 

 veins about 9 on each side, conspicuous above, with a sorus on each midway to 

 the edge. Hk. Sp. 4. p. 71. 



Hab. Fernando Po. A large plant, most like N. truncatum in habit and texture, but 

 the rhizome creeping. 



:* fronds large, pinnate ; caudcx erect or suberect. Sp. 177-196. 



t Pinnce entire or slightly lobed, so that most of the veinlets unite. Sp. 177-184. 



177. N. glandulosum, J. Sm. ; st. tufted, 1 ft. or more 1., naked or slightly 

 villose ; fr. 1 foot or more ]., 4-6 in br., with 8-12 spreading pinnae on each 

 side, those of the barren fr. the largest and closest, 2-3 in. 1., -1 in. br., the 

 margin entire or slightly lobed, the base abruptly truncate and sometimes 

 auricled ; texture papyraceo-herbaceous ; rachis and under surface naked or 

 slightly villose, sometimes glandular ; fertile pinnce contracted, the main veins 

 not more than 1 lin. apart ; veinlets 4-8 on a side, with the sori close to the 

 mi drib. Ilk. Sp. 4. p. 76. Abacopteris, Fee.
