No. 30. 
CHLORIS CILIATA Swartz, var. TEXANA Vasey n. var. 
Plant annual. . 
Culms tufted, erect, compressed, glabrous, branching only at the base. 
Leaves of the stem 3 to 5; sheaths not contiguous, glabrous, conspicuously 
striate, rarely loose; blades 1 to 24 lines wide, 9 inches or less long, flat or some- 
times involute, scabrous on the margins. 
Inflorescence a short-pedunculate cluster of 4 to 6 sessile spikes. Spikes 24 to 34 
inches long, slightly spreading; spikelets in 2 rows along one side of the slen- 
der scabrous rachis, inserted in each row at intervals of about 2 line. 
Spikelets 1 to 14 lines long, truncate-cuneate, compressed. 
Glumes 4; first and second lanceolate-oblong, acute, 1-nerved (nerves scabrous 
on the back) first about one-half the length of the spikelet, second nearly as long 
as the spikelet and with a short scabrous point; third (flowering) glume very 
broadly oblong, acute, 3-nerved (2 lateral nerves nearly marginate), sharply 
folded down the middle, densely long-pilose on the median nerve and on the middle 
third of the marginal nerves, bearing below the apex a short straight scabrous awn 
about one-half the length of the spikelet; fourth (sterile) glume broadly truncate- 
cuneate, 3-nerved, glabrous, folded down the middle, awned like the flowering 
glume. 2 or 3 additional successively smaller rudimentsof glumes, of similar shape 
but unawned, often present. Rachilla short-pilose between the second and third 
glumes. . 
Flower single, hermaphrodite. Palet ovate, acute, 2-nerved, margins folded 
inward, nerves ciliate, body of the palet curved inward transversely and outward 
longitudinally. Stamens 3; anthers ovate-sagittate, { line long. Stigmas cylin- 
drical.

PLATE XXX; a, spikelet; b and c, same, with the parts spread open and the 
rachilla broken at the point of disarticulation. 
This variety (?) differs conspicuously from the type in the longer spikes; but we 
lack authentic specimens for comparison. It was collected near Brownsville, Texas, 
and probably is not found far from the coast.
