Uhizome creeping, firm, the scales brown, lanceolate. Stipes scattered, 

 15 — 25 c.M. long, often scaly. Fronds 15 — 45 c.M. long, simple or more 

 commonly with an entire, toothed or repand, often long-acuminale and rooting 

 terminal pinna and 1 — 6 pairs of stalked, lanceolate, similar but not long- 

 acuminate lateral ones; terminal pinna to 40 c.M. long, lateial ones 7 — 15 

 c.M. long, 2 — 5 c.M. broad. Texture herbaceous; surfaces naked; main veins 

 distinct to the edge; areolae copious, wilh or without free veinlels. Fertile 

 fronds similar, but the pinnae smaller and narrower, sometimes partially co- 

 vered with meniscioid sori. — Variable. 



Var. euryliasiiS: Differs from the type by its aberrant fronds 

 being in part 2-pinnate, deltoid at the enlarged base, posteriorly deeply in- 

 cised. Even the fertile fronds are sometimes 2-pinnate at the base. 



War. Foxworthyi: Fronds reduced; lateral pinnae "2, reduced, or- 

 bicular or oblong, hardly '/2 '^•M- long; terminal pinna linear or oblong, 

 linear-lanceolate when fertile, with 2 ovate lateral lobes.

 Foxworthyi : Luzon. 



{lOb) Ij. stoloiiifer, Christ, Bull. Herb. Boiss., 2« S^rie, VI, 1004. 



Rhizome stoloniferous, the stolones bearing rows of simple fronds similar 

 to the pinnae of the normal barren fronds, decurrent at the base, on stipes 

 ± 6 c.M. long. Stipes of barren fronds stramineous, 20 — 25 c.M. long, more 

 or less densely clothed with black, subulate or setiform scales. Barren fronds 

 deltoid-ovate, + 40 c.M. long, + 50 c.M. broad, pinnate. Terminal pinna 

 largest, ± 25 c.M. long, + 4V2 c.M. broad, oblong, acute, repando-lobate, 

 decurrent at the narrowed base, the lobes irregular, short, obtuse; lateral 

 pinnae distant, alternate, ± 2 — 3 on each side, erecto-patent, + 20 c.M. 

 long, 2 — 4 c.M. broad, subsessile, the base rather unequal-sided, sometimes 

 subauriculate on the lower side, the edge repando-lobate or undulalo-crenate, 

 the apex acute, the lobes + 10 on each side, short; lowest pinnae hardly 

 reduced. Texture herbaceous; costae distinct; main veins distinct when seen 

 towards the light, straight from the costa to the edge; areolae with free
