long bristles and the side nerves smooth. Male spadix large and much branched ; 
partial inflorescences panicled, cupressiform, with many secondary branches or com- 
pound spikes; ultimate spikelets inserted inside of their own spathes with a distinct 
flattened pedicel, very brittle, the largest about ?5 mm. long, with 11-12 very approxi-

almost obsolete. Leaflets very numerous, very approximate, pectinate, rigid, narrowly 
lanceolate, 20-26 cm. long, 18-22 mm. broad, with 3 costs (the side ones slender)
