is characterized by a thin suberect rhizome, rhizome and stipe paleae that are crustaceous, dark brown to black and glossy, the long stipe and the narrowly lanceolate pinna outline. The proliferous buds are borne along the rachis in the distal part of the frond. Also, the palea morphology distinguishes it from any other taxon in the region.
