292 44. NEPIIRODIUM, EUNEPHRODIUM. 



Hab. Assam, Philippines, and Malayan Isles. This includes three species of Mette- 

 nius, his glandulosum, asperum, and lineatum, which we cannot separate clearly. 



178. N. amboinense, Presl ; st. tufted, 6-8 in. 1., greyish, nearly naked ; 

 fr. 2 ft. or more 1., 8-12 in. br. ; pinnae spreading, 3-4 in. 1., ^-f in. br., cut 

 about a quarter down into bluntish slightly falcate lobes ; lower pinnae shorter 

 and deflexed ; texture papyraceo-herbaceous ; rachis and under surface slightly 

 pubescent ; veins pinnate in the lobes, with 4-6 veinlets on a side ; sori in rows 

 close to the midrib ; caps, naked. Hk. Sp. 4. p. 75. 



Hab. Philippines, Cuming, 83, 317 ; N. India, Malayan Isles ; Ceylon, Thwaites, 3390. 

 Very near N. molle, but more papyraceous in texture, and not so hairy or so deeply 

 lobed. 



179. N. Arbuscula, Desv. ; st. tufted, 4-8 in. 1., naked or slightly pubescent ; 

 fr. 12-18 in. 1., 6-8 in. br. ; pinnce close, numerous, 3-4 in. 1., --| in. br., cut a 



quarter or less down into blunt lobes, several of the lower pairs short and 

 distant ; texture herbaceous ; rachis and lower side finely villose ; veinlets distant, 

 3-4 on a side ; sori in close rows. Hk. Sp. 4. p. 74. A. Hookeri, Wall. Hk. 

 2nd Cent. t. 22. 



Hab. Mascaren Isles, Ceylon, Neilgherries, Amboyna, Philippines, Solomon Isles. 



180. N. abortivum, J. Sm. ; st. tufted, 6-12 in. 1., firm, erect, quite naked ; fr. 

 1-2 ft. 1., 6-8 in. br. ; central pinnce 3-4 in. 1., f- in. br., cut about one-third of 

 the way dow r n into close, entire, truncate lobes in. br. ; lower pinnae distant 

 and reduced suddenly to mere auricles ; texture firm, herbaceous ; racMs and 

 both sides quite naked ; veinlets 6-8 on a side ; sori medial. Aspid. Blume. A. 

 decurtatum, Kze. 



Hab. Penang, Java, Ceylon. Allied to glandulosum, but the pinnae lobed, and the 

 veins more distant. 



181. N. refractum, Hk. ; st. tufted, 1 ft. 1., naked, glossy ; fr. 12-18 in. I., 

 6-9 in. br. ; pinnce growing gradually less from near the bottom to the top, the 

 lower ones deflexed, 4-5 in. 1., f in. br., the lowest pairs very much so, the lobes 

 broad and blunt, reaching about a quarter of the way down to the midrib ; 

 texture herbaceous ; colour bright-green ; rachis and surfaces glabrous ; veinlets 

 6-8 on a side ; sori medial ; invol. minute, fugacious. Hk. Sp. 4. p. 162. t. 252. 



Hab. Brazil. Well marked by its bright-green colour and peculiar habit. A Fern 

 gathered in Trinidad by Aldridge, N. deflexum, J. Sm. MSS., has similarly deflected 

 lower pinnae, but they are narrower, and the lobes reach halfway down to the midrib. 

 It is not unlikely that this is Polyp, retroflexum, Linn., founded on Plumier's t. 68. 



182. N. latipinna, Hk.MSS. ; st. tufted, 4-6 in. 1,, slender, naked -,fr. 8-12 in. L, 

 3-5 in. br., the upper half or third lanceolate, pinnatifid, with broad, oblong 

 lobes ; below this several pinnce on each side, the largest 2-3 in. 1., ^-| in. br., 

 cut about one-quarter of the way down into broad, oblong, subfalcate lobes ; 

 lower pinnce much reduced and distant ; texture papyraceo-herbaceous ; rachis 

 and both sides naked ; veins pinnate in the lobes, with 3-5 distant veinlets on each 

 side, with a sorus about the centre of each. N. molle, /3, Benth. Fl. Hong. p. 455. 



Hab. Hong-Kong and Java. Very doubtfully distinct from N. molle. 



183. N. pennigerwn, Hk. ; st. tufted, stout, 8-12 in. 1., finely villose ; fr. 2-4 

 ft. ]., 12-18 in. br. ; pinnce numerous, spreading, 6-9 in. 1., l-l|"in. br., the apex 

 acuminate, the edge cut about a quarter of the way down to the midrib into 

 oblong falcate lobes, the lower pinnse dwarfed and distant ; texture herbaceous 

 or subcoriaceous ; rachis and under surface finely villose ; veinlets 6-9 on a side ; 

 sori medial ; caps, setose. Hk. Sp. 4. p. 82. Aspid. pennigerum, Bl. (non Sw.}. 

 A. multilineatum, Wall. N. articulatum, Moore, J. Sm. A. megaphyllum, Mett.
