 texture subcoriaceous ; vei7is oblique, occasionally branched, ^ in. apart ; sori 

 reaching from the midrib nearly to the edge. — Ilk. Sp. 3. p. 87. 



Hab. Fiji, Samoa, and Aneiteum. Differs from the last by its more oblique and more 

 distant veins and longer and scaly stems. According to Kuhn, this is the amboincnsc 

 of Willdenow.

 gradually towards both ends, 12-18 in. 1., f-1 in. br., the edge entire or very 

 sliglitly undulated, the point acuminate ; texture suljcoriaceous ; veins almost 

 horizontal, parallel, simple, or forked, 1 lin. apart; sori not touching by a space 

 either edge or midrib. — Fragm. 5. p. 74. 



Hab. Eockingham Bay, Australia. — Dallachy, Hill. 



15. A. Griffitliiamim, Hk. ; st. tufted, short, erect ; /r. lanceolate, 6-9 in. 1., 

 |-1 in. br., the point acuminate, narrowing below very gradually, the margin 

 crenato-serrate ; texture subcoriaceous ; veins distant, obscure, usually once 

 forked ; son reaching from the midrib two-tliirds of the way to the edge. — Hk. 

 Sp. 8.p.87.t. 928. 



Hab. Assam and Sikkim, ascending to 4,000 ft. — Eecognizable at once in the group 

 by its distinctly crenated margin. A plant from Penang, gathered by Mactier, agrees 

 with this except that it has a slender stem 6-9 in. 1. 



16. A. Gautieri, Hk. ; st. tufted, 1-3 in. 1. ; fr. oblong-lanceolate, 3-4 in. 1., 

 |-1 in. br., the point acute, the upper part slightly crenato-dentate, the base 

 narrowed rather suddenly to a wing which narrows very gradually into the 

 stem, sometimes with one or a pair of small oblong blunt lobes at the base ; 

 texture herbaceous ; veins | in. apart, usually once forked about the middle ; 

 sori small, distant, not reaching either edge or midrib. — Hk. Sp. 3. p. 88. t. 184. 



Hab. Island of Nissobe, near Madagascar, Gautier. — The smallest and most delicate 

 of the group. 



17. A. serratum, Linn. ; st. short, stout, erect ; fr. 1^-3 ft. 1., 2-3 in. br., acute 

 at the apex, narrowed below gradually, the margin undulato-dentate or crenate, 

 especially towards the apex ; texture coriaceous ; midrib prominent below ; veins 

 about \ lin. apart ; sori often on each, reaching about two-thirds of the distance 

 to the edge.— ^/J-. Sp. 3. p. 81. F. Ex. t. 70. 



Hab. West Indies and Guatemala, southward to Society Islands, Peru, and S. Brazil. 

 —We include three species of F^e, — his integrum, serratum, and crenulatum.

18. A. suhhastatum, Hk. ; st. tufted, 3-4 in. 1., firm, erect, naked ; //■. 4-9 in. 1., 

 1| in. br. at the base, lanceolate, with two short rounded lobes at the base, the 

 apex acute, the margin entire, the base rounded suddenly into the petiole ; 

 texture coriaceous ; veiiis immersed, inconspicuous, erecto-patent, distant, once 

 or twice forked ; sori not reaching either edge or midrib. — Hk. Sp. 8. p. 91. le. 

 PL t. 929. 



Hab. Caraccas, and gathered lately in Peru by Dr. Spruce. — Basal lobes not alwaj-s 

 obvious. Veins casually anastomosing, 



19. A. trilobum, Cav. ; st. tufted, scaly below, 2-3 in. 1., firm, erect ; fr. 1-1 ^ 

 in. 1., 1 in. br., rhomboidal, the apex acute, the base cuneate, entire, the margin 

 undulato-crenate, or the lower part deeply lobed with broad inciso-crenate 

 divisions ; texture coriaceous ; sori broad and short. — Hk. Sj). 3. p. 90. 2nd Cent.
