in the stouter lower halt', brown and glabrous above ; pale very 

 short, truncate, broad, lodicules shortly cuneate. 



Culm 40 in. long below the inHorescence, 1 line in diameter at 

 the base ; basal sheath 5 in. long, ligule 1 line, blade nearly 18 in. 

 long, i line broad at the base, involute edges sparsely pilose ; 

 blade of next higher leaf 19 in., in the upper ones rapidly 

 becoming shorter. Spikes 4 in. or less in length, common axis 

 i in. long ; pedicel stalked, spikelet 2 lines long, rhachis-joint 2 

 to 3 lines. Outer glume a little over ] in. (y^) long, the blunt 

 apex pale purple, hyaline the rest membranous greenish becoming 

 purple in lower half ; gl. II. a shade longer than the outer ; the 

 others 1 in. ; awn 1^ in. long; pale less than y^ in. 



Comes nearest to P. r>iUosa Spreng. , but is at once distinguished 

 by its long setiform leaves and membranous outer glumes.

Perennial from a hard woody rhizome ending in new leafy 

 shoots enveloped in purplish sheaths ; culm tall slender erect, 

 bearing at the upper nodes solitary or fascicled thin wiry branches 

 ending in the single spikelike inflorescence, nodes glabrous ; leaf- 

 sheaths membranous, glabi-ous, striate, rather loose, shorter than 

 the long internodes, which are shallowly grooved on the inner side ; 

 ligule short, membranous, truncate, shortly ciliate ; lamina long, 

 narrowly linear, plicate, keeled above, margin and keel scabridu- 

 lous, apex setiform ; spike dense, rhachis fragile, joints shortly 

 pubescent on the margin ; sessile spikelet slightly exceeding the 

 rhachis-joint, ovate-lanceolate, glabrous except for the shortly 

 densely ciliolate marginal keels of the outer glume; outer glume 

 emarginate with a dark balsamiferous streak just inside the 

 keels ; pedicelled spikelet similar to the sessile hut slightly smaller, 

 and barren. 



Stem to 4 ft. in height, with internodes 4 to 10 in. long ; 

 sheaths passing gradually into the blades which may exceed 1 ft. 

 in length, with a width of 1 line gradually diminishing to the 

 setiform ajjex. Spikes 3^ in. long or shorter, by 1 line wide ; 

 I'hachis-joint 2 lines long by I line wide ; sessile spikelet 2^- lines 

 long ; gl. I. ovate-lanceolate with an almost flattened faintly 5- 

 nerved back and sharply inflexed keeled margins, embx-acing the 

 inner subequal barren glume, which is membranous, transparent, 

 scaphoid, acute, with keeled midrib and two submarginal nerves
