 larger and more compound ; lowei pinnce deltoid, 1 ft. or more 1. ; racMs broad- 

 winged above, often free below; sori sometimes immersed, — A. latifolium,-

Hab. Cuba and Mexico southward to Brazil and Peru, Polynesian and Malayan 

 Islands, Himalayas (up to 4,000 ft.), N eilgberries, Ceylon, Mascaren Isles, Zambesi-land, 

 Angola, Guinea Coast. — This includes all the Ensagenice (six species) of Moore's Index. 

 The extremes differ in size very much, but all the forms appear to agree in sori and 

 venation. Grammatosorus BlumecmviS, Eegel, Gartenfl. 1866, p. 38S, is probably a form 

 of this with abnormal sori. 



222. N. (Sagen.) OriffitUi, Baker ; St. 1-2 ft. 1., brownish, not glossy ; fr. 3-4 

 ft. 1., with a large terminal pinna cut down nearly to the rachis in the lower part 

 into lanceolate divisions, with deep lanceolate-acuminate lobes, below this several 

 pinnse on each side, the lowest deltoid, 1 ft. or more I., by nearly as broad, deeply 

 pinnatifid above, pinnate below ; texture papyraceo-herbaceoiis ; main veins dis- 

 tinct to the edge, with copious free included veinl^s ; sori rather large, in twa 

 rows, nearly all terminating free veinlets. 



Hab. Burmah, Qriffiih. — This cornea nearest the largest forms of the preceding,_but 

 the venation is closer, and it has copious free veins, and sori not on the connected veinlets. 



223. N. (Sagen.) simulans, Baker; st. tufted, 1-1§ ft., castaneous, naked, like 

 rachises ; basal scales linear, dark-brown yfr. deltoid, lJ-2 ft. each way, tripin- 

 natifid ; lowest ^rarecB largest, deltoid, stalked, with several large lanceolate deeply 

 pinnatifid^2»n?. ; texture thin but firm ; surfaces naked, bright-green ; areola few, 

 except costal arches ; sori medial, uniseriate near ribs, terminal on free veins ; inv. 

 large, glabrous. — N. giganteum, edit. 1, ex parte. Sagenia Thwaitesii,^ec?c?. F.S.I.

Hab. Ceylon, Thwaites, C. P. 3331, Wall. — The true giganteum has grey rachises, 

 compital sori, and Pkocnemiq, venation. 



224. N. (Sagen.) maeroph^llum, Baker ; st. tufted, 1-2 ft. 1., dull brownish, 

 scaly below ; fr. 2-3 ft. 1., 1 ft. or more br., with a large' terminal pinna, often 

 forked at the base, and 4-8 lanceolate-oblong lateral ones on each side, 6-12 in. 1., 

 1-3 in. br., entire or slightly lobed, the lowest pair forked at the base ; texture 

 papyraceo-herbaceous ; rachis and both surfaces usually naked ; primary veins 

 continued nearly to the edge, with numerous fine areolae with free included 

 veinlets between them ; swi in 2 rows between each primary vein. — Aspid. 

 Swz. Hk. Sp. 4. p. 56. 



Hab. Tropical America, from Cuba and Mexico to Brazil and Peru. — The Malayan 

 A. Hamhei, Presl, is either a form of this or very near it. 



Gen, 45. Nbpheolbpis, Schott. 



&»•«' round, arising from the apex of the upper branch of a vein, generally 

 near the edge. Imiiol. reniform or roundish. Veins in all free, the fronds simply 

 pinnate, with the pinnae articulated at the base and often very deciduous in the dried 

 plant, with white cretaceous dots on the upper surface. Belts the world in the 

 Tropics, passing a little beyond them both north and south. Tab. V. f. 46. 



1. N. cordifolia, Presl ; caud. suberect or oblique, the wiry fibres often 

 bearing tubers ; st. tufted, wiry, 1-4 in. 1., slightly scaly ; fr. 1-2 ft. 1., 1^2 in. 

 br. ; pznnce close, often imbricated, about 1 in. 1., J-| in. br., usually blunt, the 

 edge entire or slightly crenate, the under side rounded or cordate, the upper 

 distinctly auricled at the base ; texture subcoriaceous ; rachis slightly scaly ; both 

 sides nearly naked ; sori in a row about midway between the midrib and edge ; 

 invol. firm, distinctly reniform, oblique or opening towards the outer edge.—
