Fig. u'. 



spadix of the original spécimen on which Enoler based 

 this species and I hâve found that each pistil was provided 

 with stalked, very thick, obconical staminode (fig. u); the 

 masculine flowers are 4 — 6-angular, consisting mostly of 

 4 stamens with a thick connective hiding the thecae (fig. u').
