I first saw this plant in May 1826, at Frayle Muerto and 
Zanjon in the province of Cordova, at a distance of 360 miles 
from Buenos Ayres, and it was afterwards found by Gillies 
and Tweedie in the same province, but their specimens are of 
more slender growth, the stems more virgate and herbaceous, 
the leaves more distant, narrower, more pubescent and glau- 
cous than the plants I met with, which in habit closely resem- 
ble those collected in Texas. The root is repent, knotty 
and woody, throwing out several erect shoots at intervals, 
which are from 6 inches to a foot in height : the radical leaves 
have a slender petiole as long as the blade, being altogether 23 
inches long, and 4 lines broad, the cauline leaves have a petiole 
scarcely a line in length, and are from 10 to 16 lines long, 
about the length of the internodes, and are 2 to 5 lines broad, 
veinless, erect, and together with the stem, are almost gla- 
brous, the younger leaves and branches are, however, covered 
more or less densely, with short, rigid, spreading, and glutinous
