irregularly approximate with short and long vacant spaces interposed, linear-lanceolate 
or lanceolate-ensiform, smooth beneath or with a few very small spinules only along 
the mid-costa; the upper surface with the mid-costa spinulose and the side nerves 
naked or sparingly  spinulose. Female spadiz with the axial parts between two 
inflorescences strongly clawed, Partial inflorescences small with few arched and deflexed 
spikelets. Fruit ovoid conically beaked, 15 mm. long, 9 mm. broad; scales in 15-16

rather acute angle, with vacant spaces variable from 2-7 cm., papyraceous, rather 
rigid, very narrowly lanceolate, the largest about 20 em. long, 18-20 mm. broad, with 
3 bristly spinulous nerves beneath and the mid-costa only brist!y spinulous above. Male 
epadiz elongate flagelliform. Partial inflorescences lax, rather large with many spreading 
elongate arched spikelets on each side. Male Jlowers faleate, very acute,
