Fronds 3-pinnate. Ultimate leaflets ± 12 — 20 c.M. long, ± l—Vi^ 

 c.M. broad, linear-lanceolate, acuminate or acute, the edge serrate, the base 

 ovate-cuneate, broadest on the upper side, the petiole squamulose. Texture

 long, 2 — 5-piunate at the base, the ultimate rachises distinctly winged. Lower 

 pinnae largest. Leaflets 1 — 2V2 c.M. long, '/j — 1 c.M. broad, oblong, blunt 

 or acute, the base cuneate, the edge crenate, serrate or toothed. Texture
