This little plant usually first appears as a rosette of oblanceolate to obovate, white- 
hairy leaves, with ovoid heads of small yellow flowers subtended by silvery white 
bracts. Later the slender and decumbent stems with smaller opposite leaves appear, 
and the plant spreads to 10 to 20 cm. indiameter. In the type locality it is rarely larger 
than this, probably because it is eaten by stock,
