* (1) A. sitigaporianum. Wall., Christ, Parnkr. d. Erde, 

 227; Bedd., Ferns Br.I., II, tab. CLXVIII; Nephrodium sitigaporianum, Bh., 

 Hk. Bk., Syn. Fil., 296; Hk. & Grev., Ic. Fil., tab. XXVI. 



Rhizome short-creeping or erect. Stipes subtufted, those of the fertile 

 fronds 15 — 30 c.M. long in the unwinged part, scaly below. Fronds to 30 

 c.M. long or longer, 5 — 10 c.M. broad, the fertile ones not rarely more or 

 less smaller than the barren ones, oblong, entire, acmninate, narrowed rather 

 suddenly in the lower part and then decurrent at the base so as to form a not 

 very long wing to the highest part of the stipe. Texture papyraceo-herbaceous 

 to subcoriaceous ; main veins distinct nearly to the edge; areolae copious, 

 subquadrangular, divided into irregular-shaped smaller ones, with free veinlets. 

 Sori numerous, often ranged in lines which are subparallel to the costa, 

 4 — 6 in a line between the main veins. 



Malaya; China. 



(2) A. tricuispe, Bedd,, Handb. Ind. Ferns, Suppl., 44. 



Rhizome stout, erect. Stipes 20 — 45 c.M. long, naked or nearly so, winged 

 upwards. Fronds 25—30 c.M. long, 15 — 20 c.M. broad, deeply 3-lobate. 

 Lobes lanceolate, long-acuminate, the lateral ones 12 — 15 c.M. long, 4 — 5 c.M. 

 broad, the central one + 25 c.M. long, 6'/2 — ^'/i c.M. broad; margins entire. 

 Textui'e papyraceo-herbaceous ; surfaces slightly pilose on the costae and veins 

 beneath; main veins prominent nearly to the margin, connected by prominent 

 transverse veins, between which are copious small areolae with free veinlets. 

 Sori small, copious; indusium rather persistent.
