Acaulescent palms with large leaves; inflorescence erect; fruit with a crown of black bristles in the distal third. (

This is a monoecious palm, (has both sexes on one plant). A heavily armed petiole, the thorns in the lower parts are winged. The inflorescence, which is surrounded by a hairy brown sheath, with needle-like thorns, has the male flowers at the upper - and the female flowers at the lower side. The fruits are brown, oblong - ellipsoid; the mesocarp is bright yellow while the endocarp is black. The dry outside of the fruit burst open like a star, exposing the black stone-like seed. A palm of the undergrowth, acaulescent, (appearing stemless), the stem is actually underground, and most of it shaped like a saxophone, this is a tillering palm, (it has a heel). These palms collect falling canopy litter, and it concentrates at the base of the plant. Editing by edric.
