Stipes ± 60 c.M. long, black-purple, prickly, densely fulvo-tomentose like 

 I lie rachis, the base hidden among the long, linear, whitish-stramineous scales 

 of the trunc, the prickles scattered, acute. Fronds + 2 M. long, + 1^2

 broad, abruptly acute. Pinnulae 2 — 2^2 c.M. broad, abruptly acuminate. Ter- 

 tiary segments sessile, ± 5 m.M. broad, the base cordate, the edge serrulate, 

 the apex subacute, the higher ones adnate at the base. Texture herbaceous; 

 surfaces naked, but the under side scaly on the costae and some times on the
