 Kze, Bot. Zeit., i848, 145; A. scolopendrioides, MuelL, Pap. PI., IV, 81. 



Rhizome ± creeping or climbing, the scales dense, brown, lanceolate, 

 acuminate. Stipes 1 — 15 c.M. long, more or less scaly, especially below. 

 Fronds lanceolate, 40 — 120 c.M. long, o'/j — 7 72 c.M. broad, with the apex 

 caudate or acuminate, often proliferous, gradually narrowed below into a 

 rather subtruncate base, the margin entire or nearly so. Texture thin to 

 subcoriaceous ; costa slightly scaly below; veins oblique, simple or branched. 

 Sori occupying the lower ^3 of the veins or reaching nearly to the edge.

Rhizome creeping, clothed with lanceolate scales. Stipes approximate, 

 2 — 5 c.M. long, firm, scaly in the lower part. Fronds 15 — 25 c.M. long, 

 2 ^2 c-M. or more broad, lanceolate, the point acute, the edge slightly crenato- 

 serrate upwards, the lower part narrowed into the stipe gradually. Texture 

 herbaceous; veins usually simple. Sori numerous, narrow, extending from 

 the midrib to the margin. 



Java, Celebes. 



* (8) A. ispatliulatuiti, nu., Ann. of Bot., VHI, 124. 



Stipes short, to 5 c.M. long, approximate, slightly scaly, the scales few, 

 small, lanceolate, + adpressed, blackish or brownish. Fronds simple, ± 

 25 — 55 c.M. long, 3 — 9 c.M. broad in the upper half, which is oblong-lanceo- 

 late, cuspidate, crenate or repando-crenate but more conspicuously towards 

 the apex; near the middle the frond is rather suddenly narrowed into the 

 wing-like lower half, which is 1 — 2 '/a c.M. broad and decurrent upon the 

 stipe. Texture membranaceous to papyi'aceous ; surfaces naked; costa promi- 

 nent and clothed beneath with 2 opposite rows of small, distant, + spreading 

 scales; veins parallel, nearly spreading, simple or forked, reaching the mar- 

 gin. Sori narrow, occupying the lower '/^ — Vs of the veins; indusiura nar- 

 row, membranaceous, pale-coloured when young, at length recurved.
