obliquely truncate ; texture subcoriaceous ; rachis firm, compressed and winged 

 above ; central veins once forked ; sori in 2 regular rows, falling short of the 

 edge. Hk. Sp. 3. p. 106. 



Hab. Sandwich Islands. Very near A . compressum, but less robust. 



81. A. compressum, Swartz ; st. tufted, stout, erect, 6-8 in. L, clothed with 

 scales in the lower part ; fr. 2-3 ft. L, 8-12 in. br., lanceolate-oblong, with 10-20 

 sessile pinnae on each side, which are 6-8 in. 1., 1 in. or more br., acute or 

 bluntish at the point, the edge slightly crenatq-dentate, the upper ones decur- 

 rent at the base upon the stout fleshy compressed rachis, the upper side narrowed 

 suddenly at about a right angle, the lower one obliquely truncate ; texture her- 

 baceous ; veins distant, often twice forked ; sori broad, distant, not reaching 

 either the midrib or edge. Hk. Sp. 3. p. 121. Fil. Exot. t. 76. 



Hab. St. Helena. Pinnae often proliferous from the upper surface (A. faecundum, 

 Kunze). 



82. A. vomeriforme, Hk. ; st. 1 ft. L, naked, firm, erect ; fr. 18 in. L, 6 in. br., 

 lanceolate, with about a dozen stalked horizontal pinnae on each side, which 

 are 3 in. 1., 1 in. br., acute at the point, the edge nearly entire, the base cordate 

 on the upper, slightly truncate or rounded on the lower side ; texture subcori- 

 aceous ; veins immersed, inconspicuous, oblique, often twice forked ; sori long, 

 but falling considerably short of the edge. Hk. Sp. 3. p. 109. t. 162. 



Hab. Peru, Matthews, 1851. The alliance of this is with the two preceding, but the 

 pinnae are cordate on the upper, rounded on the lower side at the base. 



83. A. macrosorum, Bert. ; st. tufted, 4-6 in. 1., scaly at the base, naked and 

 polished and nearly black upwards ;fr. 6-12 in. L, 3-4 in. br., cordate-acuminate, 

 with a large terminal pinna, which is 4-6 in. 1., 1-1^ in. br., deeply crenate and 

 cuneate at the base, and 2 or 3 pairs of similar lateral ones, which are slightly 

 stalked, and the lowest subdeltoid ; texture subcoriaceous ; rachis and midrib 

 dark-coloured and polished like the stem ; veins distant ; sori broad, not reaching 

 either the midrib or the edge. Hk. Sp. 3. p. 93. t. 176. 



Hab. Juan Fernandez ; gathered by Bertero and Philippi. 



84. A. nitens, Swartz ; st. scattered, 6-9 in. 1., firm, erect, chesnut-brown, 

 polished, naked ; fr. l|-2 ft. 1., 6-9 in. br., with 12-20 ascending or subfalcate 

 pinncs on each side, which are 4-6 in. L, -1 in. br., the point much acuminated, 

 the edge finely toothed, the base broadly rounded on the upper, truncate in a 

 curve on the lower side ; texture subcoriaceous ; rachis naked, shining ; veins 

 oblique, often twice forked ; sori in close regular rows, not extending more than 

 halfway from the midrib to the edge. Hk. Sp. 3. p. 167. 1. 195. 



Hab. Mauritius and Bourbon. This and the two next, like species 76 and 77, resemble 

 the falcatum group in habit and texture. 



85. A. platybasis, Kunze ; st. scattered, 4-8 in. L, strong, erect, channelled, 

 the lower part scaly ; fr. 12-18 in. L, 6-9 in. br., with 12-20 erecto-patent pinnce 

 on each side, which are 4-6 in. 1., f-1 in. br., acuminated at the apex, the edge 

 serrated, the two sides unequal, the upper one narrowed suddenly at the base, 

 the lower one obliquely truncate ; rachis strong, erect, nearly naked ; veins close, 

 oblique ; sori copious, touching the midrib, but falling short of the edge. 

 A. falcatum var. Hk. Sp. 3. p. 160. A. firmum, Fee, non Kunse. 



Hab. St. Helena. Differs from A. Serra mainly by its more copious sori. 



86. A. Serra, Langs. & Fisch. ; st. distant, 6-12 in. 1., firm, erect, chesnut- 

 coloured, polished, the lower part scaly ; fr. 2-4 ft. 1., 6-12 in. br., with 12-20
