which is naked above, and surrounded by a spathe which is con¬ 
volute below. Floral envelopes none. Anthers crowded and 
somewhat whorled on the spadix, almost sessile, 2-4-celled. 
Ovaries distinct, 1-celled, with a nearly sessile stigma: ovules 
few, orthotropous, erect in the American species § Aris^ma. 
Berries distinct, 1 - several-seeded. Embryo in the axis of albu¬

of unknown meaning.)

nip-shaped, wrinkled, farinaceous, but with an intensely acrid juice. 
Spathe with the petioles and sheaths green, or frequently variegated

Anthers sessile, naked, covering all the upper part of the spadix, 
with 5 or 6 cells surrounding the margin of a thick and truncate
