 -Mm heteroclitum, Pr., (oldest name) ; — var. eurybasis, Christ, Philipp. .Tourn., 

 [I, 1S9; — var. Poxworthyi, Christ, I.e., 160. 



Rhizome 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, tqothed or repand, often long-acuminate and rooting 

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

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

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

 distinct to the edge; areolae copious, with or without free veinlets. Fertile 

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

 vered with meniscioid sori. — Variable. 



Vap. eurybasis: 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 ^-pinnate at the base. 



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

 bicular or oblong, hardly '/a ".M. long; terminal pinna linear or oblong, 

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



Trop. ^ Subtrop. Asia; Melanesia; — var. eurybasis: Mindanao; — var. 

 Foxworthyi: Luzon. 



(106) li. stolonifer, Christ, Bull. Herb. Boiss., 2" Sivie, 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 

 ieltoid-ovate, + 40 c.M. long, ± 30 c.M. broad, pinnate. Terminal pinna 

 largest, + 25 c.M. long, + 4'/2 c.M. broad, oblong, acute, repando-lobate, 

 Recurrent 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 

 subauricuiate on the lower side, the edge repando-lobate or undulalo-creuate, 

 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
