Main rachis slender, ochraceous. Primary petioles ± 3 c.M. long, nar- 

 rowly winged. Pilinulae stalked, 5— 4-lobate, the stalk ± V2 c.M. long, 

 winged, the cenlral part undivided; lobes pedately arranged, ± 9 c.M. long, 

 + 6 m.M. broad, patent, thinly marginate, the basal ones deflexed. Texture 

 coriaceous; coslulae slender, distinct, rufo-stramineous ; veins prominent,

Wa.r. crista-tiiiin : Marginal strand very indistinct, apparently want-

 Guinea by Prof. Dr. Treub and those cultivated in the Buitenzorg gardens 

 have the laciniae narrower than in the typical form, the fertile spikes parti-
