 texture herbaceous ; rachis and under side finely villose ; veinlets immersed, about 

 8 on a side ; sori medial ; invol. small, fugacious. 



Hab. Cayenne, Leprieur. 



B. Group ofN. conterminum. Lower pinnce conspicuously reduced. Sp. 44-65.

 upwards ; fr. 6-9 in. 1., 1-2 in. br., lanceolate ; pinnce distant, ^-1 in. 1., 

 l|-3 lin. br., the point bluntish, the edge more or less deeply pinnatifid, the 

 lobes sometimes close and linear-oblong, sometimes distinct, linear, or spathulate ; 

 texture papyraceo-herbaceous ; rachis naked ; under side slightly glandular ; 

 veinlets simple ; sori minute ; invol. very fugacious. Polyp. Sw. Hk. Sp. 4.

Hab. West Indies and Guatemala.

 fr. 8-10 in. 1., 1^-2 in. br. ; pinnce 1 in. L, J-f in. br., blunt, cut down halfway

Hab. Philippines, Cuming, 251, 272. An obscure plant. 



46. N. (Last.) canum, Baker ; st. densely tufted, 6-8 in. L, slender, finely 

 villose ; fr. 8-12 in. L, 3-4 in. br. ; central pinnce 2 in. 1., ^ in. br., gradually

 Lastrea, J. Sm. 



Hab. Himalayas. Habit of N. molle, but a more slender plant, with gradually-reduced 

 lower pinnse and free veins. If it is Wallich's canum at all, it is so in part only, as some 

 of the specimens clearly belong to N. molle. 



47. N. (Last.) Beddomei, Baker ; rhizome slender, wide-creeping ; st. 6-9 in. 

 L, slender, glossy; fr. 6-12 in. 1., 3-4in.br., oblong-lanceolate; central pinnce 

 the largest, 1^-2 in. 1., in. br., cut down to the rachis into close, rather acute, 

 entire lobes under 1 lin. br. ; lower pinnce distant and dwindling down very 

 gradually ; texture firm ; veins beneath villose ; veinlets 4-5 on a side, the sori 

 close to the incurved margin. A. gracilescens, Thwaites (vion Blume], L. gra- 

 cilescens, Beddome, t. 110. 



Hab. Neilgherries, Ceylon (C. P. 1287), and Java. This comes nearest the next 

 species, but is smaller and more slender, with much fewer veins, and the texture is 

 firmer. 



48. N. (Last.) Noveboracense, Desv. ; rhizome slender, wide-creeping ; st. 

 about 1 ft. 1., slender, stramineous ; fr. 1-2 ft. L, 4-6 in. br. ; pinnce spreading, 

 2-3 in. L, \ in. br., cut down very nearly to the rachis into linear-oblong lobes,
