large clumps as does the nothern form; the thick scaly root- 
stocks, usually so manifest in the type, are almost entirely want- 
ing in this form. The spikelets are smaller, hardly 3 mm. long, 
and the branches of the panicle much shorter than in any form 
hitherto observed. These differences, together with its more 
southern range, would seem to warrant its separation as a variety. 
CHLoRIS TEXENSIS n, sp. 
Smooth and glabrous, light green. Culms 3-6 dm. tall, flat- 
tened at the base; sheaths compressed, those at the base of the 
culm short and crowded, the uppermost one elongated; leaves 2.5— 
15 cm. long, 2-6 mm. wide, smooth beneath, scabrous above and 
on the margins, obtuse; inflorescence usually exserted; spikes 5-8, 
10-18 cm. long, pilose at the base; rachis triangular, scabrous 
on the angles, flexuous; spikelets about 4 mm. long, exclusive of 
the awns; empty scales narrowly lanceolate, acuminate, I-nerved, 
scabrous on the keels, the first about two-thirds as long as the 
second which about equals the third scale; third scale slightly less 
than 4 mm. long, lanceolate, 3-nerved, ciliate on the margins 
toward the apex, the rough awn 6-8 mm. long, inserted just below 
the apex, the keel sometimes sparingly pubescent, scabrous 
toward the summit; fourth scale 2-3 mm. long, lanceolate, the 
acute apex about even with the summit of the third scale, the 
scabrous awn 4-5 mm. long, inserted just below the apex. 
Collected in Texas by both Thurow and G. C. Nealley. 
Related to C. verticillata Nutt., but abundantly distinct The 
generally longer and narrower leaves, the spikelets more appressed 
to the rachis, the narrower and differently shaped third and fourth 
Scales readily separate it from that species. In C. verticillata the 
third scale is 2.5 mm. long or less, and the fourth scale not over 2 
mm. long, obovate or obovate-cuneate, truncate or obliquely so 
at the apex. 
A new Achimenes from Bolivia.
