Sori linear, submarginal, on a receptacle connecting the vein tips, com- 

 monly continuous around the sinuses. Indusium linear, consisting of the re- 

 flexed, modified margin. Spores 2-lateral. 



Rhizome wide-creeping; stipes polished, stramineous to purplish, not 

 articulate to the rhizome. Fronds at least 2-pinnate; lowest pinnulae shorter 

 than the next in order, stipule-like, close to tlie main rachis; veins free or 

 anastomosing. Diels, in Engl. & Prantl, Nat. Pfl.Fam., I'', fig. 153, F. 



Pantropical and farther south. 



(1) H. montana, Copel., Polypod. Pbilipp., 104. 



Rhizome wide-creeping, beset with minute, brown scales. Stipes firm, 

 10 — 20 c.M. high, erect, black-brown. Fronds deltoid, 15 — 30 c.M. long, 

 often broader than long, 2 — 3-pinnatifid. Lowest pinnae somewhat larger than 

 the next following ones, pinnate. Pinnulae sinuate or pinnatifid, the lowest 

 close to the rachis. Lobes often deltoid-ovate, obtuse, entire. Texture coria- 

 ceous; veins prominent above, anastomosing. Indusium broad; margin every- 

 where rolled in, giving the segments a lomarioid appearance.

Rhizome wide-creeping, clothed with narrow, linear-lanceolate scales. Stip- 

 es distant, stout, erect, sometimes slightly muricate towards the base, 8 — 150 

 c.M. long. Fronds 10 — 600 c.M. long, or even longer (!), 2 — 3-pinnate at the 

 base, often scandent or twining in the largest forms, with long, spreading, 

 rigid branches. Central pinnae opposite, with numerous, lobed or pinnatifid 

 pinnulae ± V\^—l^\^ c.M. long, ± 8—20 m.M. broad, the lowest pinnulae 

 shorter, adpressed to the rachis, reduced in size, stipule-like, lowest pinnae 

 more compound. Texture herbaceous to coriaceous; surfaces naked or the 

 under one glaucous; veins free or anastomosing. 



Var. aurita : Stipule-like pinnulae quite entire.
