Gen. char. Sori non-iudusiate, globose (rarely oblong) ; the receptacles punctiform (rarely oblong,) situated at the apex of the 

 lower anterior venules, or of the simple excurrent free veinlets, one being included within each areole. Veins forked or pinnate from a 

 central costa ; the lower anterior venules usually free and fertile, the rest angularly or arcnately anastomosing (in one or more, frequently 

 several series), and producing from their angles free excurrent veinlets which are often fertile j the marginal veinlets free. 



Fronds simple, pinnatifid, or pinnate, herbaceous or coriaceous, sometimes scaly, the fertile often much narrower. Sori trans* 

 versely uni-bi-or tri-serial, sometimes squamiferous ; Rhizome creeping, the fronds articulated, (Moore). 



1. GONIOPHLEBIUM AM^ENUM (Wall) Caudex creeping, densely paleaceous, with ferruginous subulate scales, stipites 

 a span to a foot or more long, stramineous or brown, fronds 1 to nearly 2 feet long, 6-10 inches wide, glabrous or sub-pubescent, ovate 

 terminating in a lanceolate acuminate sub-entire segment, deeply pinnatifid to within 2-3 lines of the costa, segments horizontal more or 

 Jess approximate 3-6-8 inches long, \-\ an inch wide, sub-falcate from a broad base, ensiform gradually acuminate, entire, or coarsely 

 dentato-serrate, lowest pair deflexed, veins forming one costal series of moderately sized soriferous areoles, and sometimes two (the second 

 not soriferous), marginal veinlets free, soriferous veinlet always arising from the vein at a distance from the costa, sori sub-globose sunk)
