7. A. simatum, Beauv. ; st. tufted, grooved in front, short, erect ; jr. lan- 

 ceolate, 1-2 ft. 1., 1-2^ in. tr., narrowed to an acuminate apex and very gradually 

 below, the margin slightly undulated but not toothed ; texture coriaceous ; veins 

 1 lin. apart, usually simple ; smi narrow, often on every vein, reaching from near 

 the rachis nearly to the margin. — Hik. Sp. 3. p. 82. Fil. Esc. t. 61. 



Hab. Guinea Coast southward to Angola. — A. venosum, Hk., does not seem safely 



8. A. Currori, Hk. ; st. scarcely any ; fr. lanceolate, 12-18 in, 1., IJ in. br., 

 narrowed gradually to an acuminate apex, but suddenly at the base, the margin 

 slightly undulated ; texture subcoriaceous ; veins fine, usually once branched, 

 about J in. apart ; sori not reaching by a space either midrib or margin. — Hh. 

 Sp. 3. p. 82. 



Hab. Guinea Ooast ; gathered by Curror, Barter, and Mann. — Distinguished from 

 the last by its more distant and usually branched veins and broader sori. 



9. A. coriaeeum. Baker ; st, tufted, 2-3 in. 1., firm, compressed, winged ; fr. 

 0-12 in. 1., 14 in. br., much acuminated at the apex, the edge very nearly entire, 

 narrowed below gradually into the winged stem ; textiwe very coriaceous ; veins 

 obliq^ue and curved, branched at the base and again at or above the middle, so 

 that at the edge the veins that originate from one are J-f in, apart ; sori distant, 

 very oblique, generally § in. 1. 



Hab. Cameroon Mountains, Q. Mairm. 



10. A. squamulatvm, Blume ; st. tufted, 2-4 in, 1,, strong, erect, scaly below ; 

 fr. lanceolate, 12-18 in. 1., 2-3 in. br.j narrowed to an acuminate apex and very 

 gradually below into the stem, the margin entire ; texture yery coriaceous ; veins 

 inconspicuous, 1 lin. apart, usually simple ; sori reaching from near the midrib 

 to ^^ in. of the margin ; rachis stout, pale, the lower part furfuraceous. — Jii:. 

 Sp. 3.^7.82. 



Hab. Java, Borneo, Philippines. — Habit of A. Nidus, but the veins falling short of 

 the edge. 



11. A. scolopendrioides, J. Sm. ; st. short, erect, scaly ; fr, lanceolate, nearly 

 1 ft. 1., IJ-lJ in. br., narrowed suddenly above to a long caudate apex, very 

 gradually into the stem below, the margin entire ; texture subcoriaceous ; veins 

 oblique, usually simple, 1 lin. apart ; sori reaching from the midrib to within 

 J in. of the margin ; invol. leaving a distinct elevated ridge on the frond when it 

 separates. —Hk. Sp. 3. p. 84. Ic. PI. t. 930. 



Hab. Philippines, Cuining, 318. — A fragment from Borneo exhibits the same raised 

 line where the involucre bursts, but the stem is much longer. Doubtfully distinct from 

 Sp. 13, with which it corresponds in texture and venation. 



12. A. vittceforme, Cav. ; rJiinome creeping, naked ; st. short, erect, naked ; 

 fr. lanceolate, 12-18 in. 1.,, 1^-3 in. br., narrowed to an acute point and ve'ry 

 gradually into the stem below, the margin obscurely toothed ; texture coriaceous ; 

 veins simple, close, nearly horizontal, the copious sori often reaching from the 

 midrib nearly to the edge. — A. sundense, Blume. Mk. Sp. 3, p. 85. 



Hab. Java, Philippines, I'iji. — An authentic example of Brackenridge's A. cmboinense 

 agrees with this. This belongs to the genus Micropodium of Mettenius, which includes 

 the Aspkmea with the mode of growth oi EupolypocUum [Eremobrya, J. Smith). 



13. A..fejeense, Brack. ; r?iizome wide-climbing ; st. 6 in 1., scaly below ; fr. 

 lanceolate, 18-24 in. 1,, 1^-2 in, br., caudate or acuminate, often proliferous at
