E 'up to 12 m high, has a trunk diameter of 40 cm, wider at the base. The leaf has a stalk of about 1.5 m with margins serrated edges and prominent, in the attack on the barrel is covered with a thick reddish-brown fabric.
The lamina and palm with a radius of 1.5-2 m, concave top and divided into 70-80 segments and mid-green, stiff, about 3 cm wide and incised at the apex. 
The inflorescence, with hairy Spata, is as long as the leaves or slightly less, branched (with 3 orders branches). The fruits are globose, mucronate, about 3.5 cm in diameter, the first green then yellow, then blacks and edible when ripe. 
seeds which are the hardest I've ever work, especially because of the presence of a 'shield' protective only after 1 hour and more than polishing (electric, I dare not think of pedals) are beginning to reveal white exterior; even more special is the point of attachment of the petiole, botanically called a beak, forming a mass within the seed darker undetectable externally.
