Primary petioles sbort or obsolete, secondary ones \ — 1 ^/j c.M. long. Pinnae 

 20—30 c.M. long, 10—15 c.M. broad. Pinnulae uniform, 9—12 on each side, 

 5 — 7^2 c.M. long, to 2 '/a -c.M. broad, articulate at the base, pinnatifid through- 

 out more than half-way down to the costa into close, entire, blunt lobes 

 + 5 m.M. broad; upper pinnulae sessile, lower ones short-stalked. Texture 

 subcoriaceous ; rachis and surfaces pubescent. The fruit in the fertile pinnulae 

 occupying the back of the scarcely modified lobes. Spores verruculose.

Primary petioles very short, secondary ones 1 — S'/j c.M. long. Pinnae 

 7*/j — 20 c.M. long, with a terminal, simple or bifid pinnula and 4 — 6 lateral 

 ones on each side. Pinnulae alternate, stalked, articulate at the base, 2 ~3 72 c.M. 

 long, ± 1 '/a c-M. broad, subtriangular or oblong, blunt, simple, entire or rarely 

 slightly lobed, the base rounded, truncate, cordate or bluntly hastate. Texture 

 thin but firm. Fertile pinnulae commonly shorter, subdeltoid, with a mostly 

 rounded apex. Spikes 2'/j — 7 '/a ^•^- lo^S' ^^ ^^^^^ ™^s- Spores reticulate.

Primary petioles short or wanting. Pimiae pinnate, 12—30 c.M. long, 

 7_22 c.M. broad, the rachis + straight and narrowly marginate, with 4—7 

 pinnulae on each side below the terminal one. Pinnulae stalked, linear-lanceo- 

 late, acute or bluntish, the edge serrulate, the base cordate, truncate or 

 rounded, the stalks nodose & spuriously articulate at the apex. Lowest pinnulae 

 sometimes pinnate with 1—3 leaflets on each side below the terminal one; 

 lateral leaflets small, subrhoraboidal, the base cordate on the lower and cuneate 

 on the upper side; terminal leaflets with the base cuneate on both sides. 

 Texture + coriaceous ; upper surface glossy, naked or slightly hairy on the 

 costae; under surface opaque; rachises rather slightly hairy. Fertile pinnulae 

 similar to the barren ones. Spikes to + 4 m.M. long. Spores verruculose.
