 Bedd., Ferns S. I., tab. CXXVI.

 serrate-dentate, acuminate, sometimes irregularly and narrowly pinnate 

 (teratophylloid).

(35a) A. prollficans, v. A. ». K., in Bull. Btz., 1913, XI, 4. 



Rhizome erect. Stipes close or approximate, + ^2'/2 — 27 '/^ cm. 

 long, dirty-dark-fuscous when dry and chaffy with scattered, deciduous, 

 dark-brown and pale-brown scales different in size, as is the rachis. 

 Fronds oblong, + 35 — 45 cm. long. Pinnae ascending, + 5—6 on each 

 side below the terminal one, lanceolate-oblong, 7 — 20 cm. long, 2 — 6 cm. 

 broad, the terminal one the largest, the lowest the smallest; terminal 

 pinna irregularly toothed towards the abruptly caudate-acuminate apex, 

 proliferous at the point, gradually entire or subentire towards the cuneate 

 and decurrent base; lateral pinnae similar but not prohferous, with the 

 lower base decurrent ; lowest pinnae shortly petiolulate. Texture thinly 

 coriaceous, rather flaccid; surfaces naked; costae more or less chaffy be- 

 neath especially at the base; veins oblique, simple or forked, thickened 

 at the apex. Sori long, often occupying the lowest '/^ of the veins; 

 indusium firm, persistent, brown. — Young plants with the fronds simple, 

 similar to the terminal pinna but much larger and not proliferous.
