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 1\ 

 inches long, and 4 lines broad, the cauline leaves have a petiole 

 scarcely a line in length, and are from 10 to IG 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
