acuminate, straight, curved or subflexuose terminal brancli + 12 '/i — H'/j 

 cm. long by 1 '/a — 2 cm. broad at or near the base and 3 — 5 erecto-patent, 

 similar but mostly shorter ones on each side. Leaflets oblique or sub- 

 spreading, approximate, oblong, the largest T'/j — 10 mm. long, 3 — 4 mm. 

 broad, the apex blunt, the lower edge straight or nearly so, the upper 

 edge lobed, the base cuneate; lobes ± 3 — 5 (mostly 5), the barren ones 

 small and rounded, the fertile ones larger (longer and broader) and 

 truncate (often dilated) at the apex. Texture thin; surfaces naked; 

 rachises when dry quadrangular and grooved at least on the upper side, 

 veins mostly forked, sometimes sparingly anastomosing. Sori terminal 

 on the fertile lobes, 1 — 3 (mostly 2) to a leaflet, solitary on the veins or 

 commonly uniting the apices of 2 — 3 veins or veinlets, if solitary, then 

 terminal on the leaflets, if 2, then 1 terminal and the other occupying 

 one of the central lobes, if 3, then occupying the terminal and next 

 following lobes; indusium rather thin, subcrenulate.

Near L. diplosora v. A. v. R. but the leaflets not rarely larger, 

 bounded by a more or less pellucid marginal strand, the lower edge 

 upcurved, the sori occupying the 1 — 3 higher lobes, the fertile lobes often 

 broade]' than the barren ones but not longer, the indusium firmer and 

 rather entire.

Stipes stramineous, naked, quadrangular, 17'/, — 25 cm. long. Fronds 

 ± 15—20 cm. long, + I2V2— H'/a cm. broad, 2-pinnate, with 2—3 

 branches on each side below the terminal one ; rachis naked, quadran- 

 gular. Branches short-stalked, hnear, acuminate, ^4 — I'/a cm. broad; 

 terminal branch + 12 Vj — 17 '/j cm. long; lateral branches mostly shorter, 

 the highest much ascending, the lowest less so. Leaflets close, erecto- 

 patent, the central the largest, ± 6. — 12 mm. long, ± \ as broad, the 

 base cuneate, the lower edge entire, upcurved, the upper edge cut + 

 •/j-way down, the base cuneate. Lobes suberect, shortly linear, '/s — 1 

 mm. broad, simple or 2-fid, slightly dilated towards the base, separated 

 by rather acute sinuses, the barren ones bluntish at the apex, the fertile 

 truncate. Texture firm-herbaceous ; surfaces naked ; veins simple or mostly
