16 cm wide, acuminate, base rounded, slightly cordate, margins rather 
coarsely toothed. Spikes unisexual, the pistillate ones dense, cylindric,

villous; styles divided into many, filiform, slender, elongated branches. 
Frequently cultivated for ornamental purposes, fl. all the year, intro- 
duced; probably a native of Malaya or of Polynesia. A striking ornamental

with shades of red, purple, and olive, the margins distinctly and regularly 
toothed. Spikes purplish, slender, the staminate ones up to 20 cm long, 
less than 5 mm in diameter, interrupted, the flowers glomerate.
