long, 3—6” broad, drawn out into a long scabrous point, bearded at the 
mouth of the sheath, otherwise glabrous. Panicle open or slightly con- 
tracted, oblong, 6—10‘ X 11/2—2'/2’, the stiff patent or suberect rays in 
whorls of 5—2, dividing from the ies upward, 11/2—21/2‘ long, very 
scabrous daodchiont, as is the sharply angular rhachis, with short teeth 
visible to the naked eye; axils ciliate. Spikelets on short pedicels of 
about '/2’, dark-green, oblong, about 1“ broad and 2"/2—5” in length, 
14—18-flowered. Outer glumes sharply serrulate on the keel, the lower 
1-nerved and rather longer than its mate, 2“, drawn out into a filiform 
point and generally equalling or exceeding the lowest floret; the upper 
one often 3-nerved. Flowering glumes ovate-lanceolate, acute, 3-nerved, 
all nerves uniting at the apex, the keel almost sm mooth. Paleae a little 
shorter, oblanceolate, entire, serrulate at the keels. — Hook. & Arn. in

The prevailing form on the mountains of Oahu! Distinguished from all other species 
by the extraordinary roughness of its rhachis and rays. The filiform points are apt to 
drop off the outer glumes, — then appear shorter than their next in you

rays 1—1!/2‘ long, all axils (even those of the secondary divisions) ciliate.

hu! The leaves are equitant in the lower portion of the stem, where they are 
much crowded, just as in the form a, but they are not cay distichous, as is readily 
seen in the upper portion 
— Panicle contracted and continuous, 7’ long, 8—9“ broad. 
Spikelets 12—14-flowered. Leaves flat.

the panicle or shorter, convolute, 2—3” br oad when unrolled, gradually 
narrowing to a peoraaiens filiform point. Panicle 8—12‘ long, contracted, 
upted, the dense fascicles shorter than their inter- 
nodes, feecaed « pete Ja‘ long; the rhachis smooth in the low er porti

the empty ones narrow-acute, 1/4 shorter than their next Sick scabrous 
on the keel, the lower 1-, the upper often 3-n erved. Flowering glumes ovate-
