Descr. Perennial. Stems much branched, and, as wellas 
the foliage, every where clothed with short, dense, glaucous 
pubescence, occasioning a hoary appearance, that suggested 
the specific name. Leaves scattered, about an inch long, 
linear-lanceolate, entire, patent or recurved, gradually be- 
coming smaller on the ultimate branches, which are termi- 
nated by a large single flower. Involucre almost globose, 
the scales numerous, linear, squarrose, slightly glandular. 
Ray of many florets, and of a bright purple colour. Disk 
deep yellow.
