(12) A. cliiuorpha, Christ, Ann. Btz., XIX, 41. 



Stipe and rachis unarmed, castaneous, angular, covered with dark, fur- 

 furaceous scales. Fronds large, + 2 M. long, ± 40 c.M. broad, 2-pinnate in 

 the barren, 5-pinnatifid in the fertile portions. Lower and higher pinnae 

 sterile and shorter, central fertile and longer. Barren pinnae ± 20 c.M. long, 

 ± 7 c.M. broad, distant, acuminate, stalked; the pinnulae stalked, with the 

 base cordate, hardly 1 c.M. broad, narrowed gradually to the point, the apex 

 acuminate, the edge slightly lobed into close, not deep, roundish or acute, 

 crenulate lobes. Texture coriaceous ; upper surface dark-green, under one paler, 

 scaly at or near the costae. Fertile pinnulae ± '/^ c.M. broad, pinnatifid 

 nearly to the costa, the lobes not close, + 5 m.M. broad, obtuse, deltoid. 

 Sori large, 5 — 6 to a lobe, occupying its whole under surface. 



Celebes. 



« (13) A. ftLingi, ClarUe, Bedd., Handb. Ind. Ferns, 47.'5. 



Fronds 3-pinnatifid ; rachises tomentose above, naked, brown, somewhat 

 glaucous beneath. Pinnae 50 — 60 c.M. long, the apex pinnatifid, toothed at 

 the point. Pinnulae distant, short-stalked, the lowest largest or a little shorter, 

 ± 6 — 8 c.M. long, + 1 — 1^2 c.M. broad, the apex acuminate and bluntly 

 crenate, the edge cut down nearly to the costa into not very close, oblong, 

 subfalcate, blunt, slightly crenate lobes, the lowest lobes ± largest. Texture 

 coriaceous; surfaces naked, of a bluish-glaucous tint; costae + scaly beneath, 

 hairy above, very prominent especially in the fertile pinnulae, which have the 

 soriferous segments mostly much smaller than the barren segments; veins 

 forked or sometimes simple. Sori in 1 row on each side of the costulae, 

 filling up the whole under surface of the fertile segments, which have the 

 edges recurved. 



Malacca. 



(14) A. l¥allacei, Mett., Hk. Bk., Syn. Fil., 4i;9. 



Fronds large, 5-pinnatifid; rachises stramineous, densely pubescent. Pin- 

 nae oblong-lanceolate, 50 — 40 c.M. long. Pinnulae ligulate, distinctly stalked, 

 5 — 5 c.M. long, ± 1 c.M. broad, cut down to a narrow wing. Segments 

 close, ligulate, blunt, obscurely toothed, ± S'/^ m.M. broad. Texture sub- 

 coriaceous; surfaces green, the under one densely pilose, with a few bullate 

 scales on the ribs; veins 4 — S-jugate, simple. Sori costulai".
