short pappus, the upper half of the tube being inflated 

 and fusiform and with rudimentary closed teeth; nerves 

 very prominent, glabrous ; style branches subulate-filiform 

 and hispid for more than half their length. This is a 

 small shrub about 1° high, branched at the base and 

 forming a rounded tuft of rather slender branches cov- 

 ered with the scale-like leaves, the flowers are cream- 

 'colored or light yellow and are clustered at the end of the 

 branches, rather corymbosely, in heads of five or more.
