"Stems clustering. Leaves pinnately divided; segments ca. 20 cm, uniform in width or terminal segments wider than other segment. Fruits black, globose, 5-8 mm in diameter, black.  The segments may be narrow or broad, terminal segments may be equal or wider than other segments, and segments may be upright or flat"  (Flora of North America online).

Habitat/ecology:  In Florida (U.S.), "moist organic soil over limestone in mesic hammocks and disturbed wooded areas; 0-10 m"  (Flora of North America online).  In Guatemala (native), "dense, wet, lowland forests at altitudes of 500 meters or less"  (Standley and Steyermark, 1958; 24(1)234-235).

Propagation:  Seed.  "The fruits of Chamaedorea seifrizii, ripening from green through orange to black, are taken by birds, and seedlings thrive in shaded, moist habitats"  (Flora of North America online).

Native range:  Belize, Mexico, Honduras (GRIN).
