 3-4 in. br., the apex pinnatifid, the lower two-thirds pinnate, with 3-5 pinnce on 

 each side, the lower ones distinctly stalked, 2 in. 1., in. br., the point acute, 

 rather falcate, the edge nearly entire, both sides narrowed suddenly, and the upper

Hab. Luzon, Owning, 199. 



208. A. (Dipl.) pinnatifido-pinnatum, Hk. ; st. 6-12 in. 1., firm, erect, naked ; 

 fr. 9-12 in. ]., 6-9 in. br., with a deltoid apex deeply lobed below, and 3-4 pinnce 

 on each side, which are 3-4 in. 1., 1 in. br., the point acute, the edge sharply 

 but not deeply toothed, the base cuneate on both sides ; texture coriaceous ; veins 

 obscure, copiously pinnated ; sori irregular, beginning at the midrib, but falling 

 far short of the edge. Hk. Sp. 3. p. 238. 



Hab. Mishmee, Griffith. In texture and dulness of colour this resembles the last 

 species and A. Brackenridgii.

 auricled ; texture herbaceous ; veins dark-green, 2-3 to a group ; sori reaching 

 from the midrib quite to the edge. Diplazium, Moore, Tnd. Fil. p. 337. 



Hab. Darien, Seemann. This has the texture and pellucid venation of A. grandlfolium, 

 but the whole plant and pinnae are much smaller, with veins only twice forked, and sori 

 running up on the unbranched fork to the edge. 



210. A. (Dipl.) lantamense, Baker ; st. 6-12 in. 1., firm, erect, nearly naked ;

 texture coriaceous ; veins 3-5 to a group ; sori slender, irregular, nearly touching 

 both edge and midrib. Diplazium, Bl. A. fraxinifolium, Wall., Hk. Sp. 3. 

 p. 240. 2nd Cent. t. 19. /3, A. alternifolium, Mett. ; pinnce broader, rounded at 

 the base ; lower veins not reaching the edge. Hk. Sp. 3. p. 239. 



Hab. Himalayas, Hong-Kong, Malaccas, Borneo, Aneiteum. Probably a free-veined 

 form of A. lineolatum.

 the base \fr. 8 ft. 1., with numerous pinnce 1 ft. or more 1., 2^-3 in. br., the point 

 acuminate, the edge slightly toothed towards the point, the base rounded equally 

 on both sides ; texture very coriaceous ; rachis strong, erect ; veins simple, close, 

 parallel ; sori beginning at the midrib, but falling short of the edge. Hk. Sp. 3. 

 p. 244 (in part}.

 the margin toothed only towards the point, the base rounded equally on both 

 sides, the lower ones stalked ; texture coriaceous ; colour bright-green ; veins 5-6 

 to a group ; sori beginning at the midrib, and reaching nearly to the edge. Dipla- 

 zium, Fee, Gen. Fil. 214. 



Hab. Cuba, Linden ; Guadeloupe, L'Herminier ; Tarapota, Peru, Spruce, 4760. This 

 rivals Lechleri in size and texture, differing totally in venation.
