Two states of this plant are found by Mr. Douglas: the one, smaller and destitute of spinous 
processes upon the stipes; the other (as now figured), larger, and furnished here and there, on the 
stipes, with short spines, which perhaps may be considered as abortive pinngs. 
The habit of the plant, as Dr. Kaulfuss well observes, is that of. Preris argentea ; and the rich 
yellow dust with which the underside is clothed is common to other plants of the present genus.
