Veins simple or the lowest anterior forked. 



A collection made in Negros Island includes the common form of 

 this with rounded pinnae. With it and connected by gradations is a 

 form with very acute long pinnae and a prominent auricle 5 mm. or 

 more long, which, if by itself, would pass easily for a distinct species. 

 In more monstruous individuals this auricle becomes almost free and more 

 than 2 cm. long, and finally several lower pairs of pinnae may break up 

 into pinnules connected only by a wing, each pinnule like a small pinna 

 of a normal frond. In such freaks, the basiscopic pinnules are the largest 

 ones. (Copel.). 



(39) A. Innulatum, Sw. 



Pinnae blunt to acute at the apex; veins mostly forked, the higher 

 sometimes simple and the lowest anterior aiot rarely pinnate.

Rhizome woody, scandent, dark-brown, clothed with numerous scat- 

 tered, adpressed, minute, blackish scales. Stipes remote, 2-seriate, when 

 dry grey-brown, naked like the rachis or sparingly appresso-squamulose, + 

 10 — 15 cm. long, apparently articulated at the base. Fronds 25 — 35 cm. 

 long ,10—20 cm. broad, subdimorphous, simply pinnate. Pinnae + 10 pair on 

 each side, subspreading to suberect, remote, petiolulate, linear-lanceolate, 

 gradually long-acuminate, the upper base more or less abruptly and 

 broadly rotundate-cuneatae to rotundate-subtruncate, the lower base nar- 

 rowly cuneate and partly cut away; central or lower pinnae the largest, 

 5 — 12 cm. long, '/a — ^% '^i^- broad, the barren ones the largest and 

 broadest, serrate-crenate, the fertile ones the shortest and narrowest, 

 subentire or crenate; terminal pinna similar to the lateral ones but 

 mostly less unequal-sided at the base. Texture herbaceous, transparent; 

 surfaces naked ; costae prominent ; veins oblique, simple or forked, numer- 

 ous. Sori numerous, close, more or less reaching nearly the costa and
