green, stout, with a ventral and two lateral furrows, tuberculate and shaggy 
at the base with a straightish and long brownish-yellow glossy pulu, 
which changes higher up into stiff long blackish hair, and as such often 
covers the entire stipes. Frond with stipes 6—12 ft. long and 3—6 ft. 
broad, pyramidal-oblong, coriaceous, naked underneath or sometimes with 
minute furfuraceous dots; the rhachis asperous with scattering tubercles. 
Pinnae with a stipes of 1—2‘, oblong, 11/2—2"/2 ft. long, bearing 18—24 pairs 
of free pinnules besides the pinnatifid apex; most pinnules shortly stipitate, 
linear-lanceolate, 5—10/  1—1!/2‘, acute, cut halfway or more, often to 
the rhachis at the base, into oblong rounded entire segments, which are 
separated by broad sinuses. Veinlets very prominent, simple or forked.

3/s—1!/4’ in width, outer valve fornicate and large, the inner flat and
