Nakai Phenakospermum amazonicum (Mart.)
Phenakospermum is a monotypic genus in the family Strelitziaceae.
Only one species is recognized, Phenakospermum guyannense, native to Suriname, French Guiana and the eastern Amazon River basin.
This plant grows to over 10 m (33 ft) in height but can be felled with a single blow with a machete.
Although not as prized as the ornamental Traveler's palm (in the same family), P. guyannense is used locally in Brazil as a landscape element.
