Description
|
Caudex usually 1-3 m. high and supported at the base by prop roots, 1.5-2 cm. thick or at the base much thicker, green, the inter- nodes chiefly short and only 1 cm. long, often armed with recurved prickles 2-3 mm. long; petioles'20-30 cm. long or more, terete above, the sheath extending above the middle; blades 15-40 cm. long or more, deeply sagittate, the basal lobes retrorse, acuminate to subobtuse, the anterior lobe triangular-ovate, broad, often cuspidate, the primary costal nerves 3-4 on each side; peduncle half as long as the spathe; spathes oblong-ovate, cuspidate, 10-15 cm. long and 6-7 cm. wide or larger, greenish or pale outside, white or whitish within; spadix very thick, the staminate portion 7 cm. long, the pistillate one-third as long; stamens 3-6; berries subglobose, 1-1.5 cm. in diameter.

CANAL ZONE and COL6N: common in swamps of the Atlantic coast, and doubtless distributed along the whole coast.
|
Note
|
Because of its peculiar habitat and characteristic leaf form, this plant is easy of recognition among other Panama aroids. The large, white spathes are con- spicuous, and somewhat suggest those of the cultivated calla (Zantedeschia). Illustrated, Standl. Fl. Pan. Canal Zone. P1. 9; Engler, Pflanzenreich IV. 23C:123. Montrichardia Fendleri was based on Fendler 432 and 433 from Chagres.
