base ; fr. 1 ft. 1., 10 in. br., with 13-15 pinnae on each side, the lower ones 5 in. 

 1., |- in. br., the point acuminate and toothed, the edge lower down bluntly lobed 

 J of the way to the rachis, the base subcuneate ; rachis and both sides naked ; 

 veins pinnate in the lobes, with 3-4 veinlets on a side ; sori medial. Fee, Fil. 

 Ant. t. 24. 



Hab. Trinidad, Germain. 



162. N. unitum, R. Br. (non Sieb.) ; st. 12-18 in. 1., brownish, naked ; fr. 2 ft. 

 or more 1., 6-8 in. br. ; pinnae 4-5 in. 1., \ in. br., the edge cut from a third to 

 halfway down into spreading, triangular, sharp-pointed lobes; lower pinnce not 

 dwindling down ; texture coriaceous ; veins pinnate in the broad lobes, with 6-8 

 veinlets on each side, with sori near the extremity principally in the lobes ; caps. 

 naked. Polyp. L. fide Mett. Aspid. Mett. Fit. Ind. p. 230. a, A. gongylodes, 

 Schk. ; rachis and under side naked. /3, A. propinquum, R. Br. ; rachis and 

 under side villose. Hk. Sp. 4. p. 79. 



Hab. Mexico and West Indies to Brazil and Peru ; Polynesian Isles ; Hong-Kong 

 and Himalayas to Australia and New Zealand ; Mascaren Isles, Natal, Cape Colony, 

 Angola, Guinea Coast, Algiers. We follow Mettenius in nomenclature, but the unitum 

 of the Linnaean herbarium is Sieber's plant, our cucullatum. 



163. N. sophoroides, Desv. ; st. 1 ft. or more L, slender, substramineous, 

 pubescent ; fr. 1-2 ft. 1., 6-9 in. br. ; pinnce spreading, 4-6 in. L, ^-f in. br., the 

 apex acuminate, the edge cut about one- third of the way down into oblong- 

 triangular subfalcate lobes ; texture papyraceo-herbaceous ; rachis and under 

 surface finely villose ; veins pinnate in groups, with 8-10 veinlets on a side, 

 with sori distant from the midrib ; caps, naked. Polyp. Thunb. A. molle, 

 Hk. Sp. 4. p. 68 (in part}. 



Hab. Japan to Hong-Kong and Formosa. Very near the preceding in the shape of 

 its pinnae and lobes, but smaller and thinner in texture, and less rigid. 



164. N. pteroides, J. Sm. ; st. 1-2 ft. L, slender, stramineous or greyish, 

 slightly scaly below ; fr. 2-4 ft. 1., 1 ft. or more br. ; pinnce spreading, 4-8 in. 1., 

 | in. br., the apex acuminate, the edge cut one-third or halfway down into 

 oblong or subtriangular lobes ; texture papyraceo-herbaceous ; rachis and both 

 sides nearly naked ; veins pinnate in the lobes, with 8-10 veinlets on each side ; 

 sori quite marginal and confined to the lobes. Polyp. Retz. N. terminans, 

 Hk. Sp. 4. p. 73. (in part). 



Hab. Himalayas, Neilgherries, Ceylon (Gardner, 1106), Malaccas, Philippines (Cuming, 

 48, 293), S. China, Queensland, Samoa. This has, like the two preceding, oblong-trian- 

 gular lobes 1^-2 lin. br., not reaching more than one-third down, and differs from them 

 by having the sori quite confined to the lobes. 



165. N. extensum, Hk. ; st. 1-2 ft. 1., naked or slightly pubescent, brownish ; 

 fr. 2-4 ft. 1., 12-18 in. br. ; pinnce 6-9 in. L, ^-f in. br., cut about two- 

 thirds down to the rachis into linear-oblong lobes; lower pinnce scarcely shorter 

 than the rest ; texture papyraceo-herbaceous ; under surface naked or slightly 

 villose ; veinlets 6-8 on a side, often only the lowest pair united ; sori in rows, 

 nearly terminal in the veins, and not confined to the lobes. Hk. Sp. 4. p. 72. 

 t. 240. A. (in part). Aspid. Bl. ! A. conioneuron, Mett. 



Hab. Ceylon (Gardner, 1362), N. India, Malaccas, Neilgherries (Beddome, t. 85), 

 Philippines (Cuming, 391). This is joined to the preceding by Mettenius. The texture 

 is more herbaceous, and the lobes are much narrower and deeper, with a considerable 

 space between them. 



166. N. Serra, Desv. ; st. 1 ft. or more 1., firm, glossy, substramineous ; fr. 

 2-3 ft. 1., 1 ft. or more br. ; pinnce spreading, 6-12 in. L, - in. br., cut down
