This palm is good deal like Bentinckia in the shape of the 
fruit, and spadix-branches, but less Arecoid, none of the 
spathes being complete; but differs in the imbricate female 
corolla, the ruminate albumen, and bilocular ovarium. 
Itis also like Geonoma, especiall in habit, but both the 
spathes are incomplete, style ¢erminal! not a berry, and the 
albumen is ruminate.
