==Description==
Solitary-trunked and covered in leaf scars, which exude a yellow gum after leaf loss. The linear leaflets are pinnately arranged and once-folded with toothed margins. The petioles and rachises feature recurved spines which hook onto vegetation and assist them in climbing. The inflorescences in both species consist of close, overlapping bracts from which male or female flowers emerge. The bracts are armed with spines and the inflorescence resembles those in Heliconia species. The small, round fruit, regarded as a delicacy by the Temuan aborigines, are scaly and usually contain three seeds. (Uhl, Natalie W. and Dransfield, John (1987)/Palmweb.

==Comments and Curiosities==
This is a [[dioecious]] specie. 

Etymology: The specific name is a combination of two Greek words meaning 'beautiful' and 'spathe'.

It is not common in collections, nor has it been found in the wild for several years, leading some to conclude that the species may have become extinct.
