numerous, narrowly lanceolate, 15-:iO cm. long, 1-1-5 cm. broad, very distinctly fascicled
and usually, at least iu the intermediate pai-t of the leaf, pointing iti difierent ways,
often many of those near thb apex subequidistant. Male spadix simply decompound
or rudimentarily supra-decompound, the spikelets bearing at each spathel a glomerule of
flowers or very short and aubscorpioid secondary spikelets •vvliich are composed of
4 - 8 flowers. Female spadix about 2 m. long, including a tenninal flagellum; epikelets
slender. Fruiting perianth explanate. Fvuit pisiform, 8-9 mm. in diam. Scales in 15
series, channelled along the middle.
