in the stouter lower half, brown and glabrous above ; pale very 
short, truncate, broad, lodicules shortly cuneate. 
Culm 40 in. long below the inflorescence, 1 line in diameter at 
the base; basal sheath 5 in. long, ligule 1 line, blade nearly 18 in. 
long, 4 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 
} in. long; pedicel stalked, spikelet 2 lines long, rhachis-joint 2 
to 3 lines. Outer glume a little over } in. (,5,) 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 } in.; awn 1} in. long; pale less than , in. 
Comes nearest to P. villosa 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, glabrous, 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 but 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 apex. Spikes 31 in. long or shorter, by 1 line wide; 
rhachis-joint 2 lines long by 3 line wide; sessile spikelet 23 lines 
long; gl. I. ovate-lanceolate with an almost flattened faintly 5- 
nerved back and sharply inflexed keeled margins, embracing the 
inner subequal barren glume, which is membranous, transparent, 
scaphoid, acute, with keeled midrib and two submarginal nerves
