Glabrous desert-plant, never tall, slightly woody ; leaves 

 very small, semicylindric-linear, greyish-green, often 

 hooked-curved at the end, somewhat succulent and de- 

 current ; headlets of flowers very small, on short stalks ; 

 involucral bracts in about two rows of almost equal 

 length ; expanding lamina of marginal flowers very 

 short; pappus tubular towards the base or with some 

 disconnected bristlets ; fertile fruits glabrous.

 marginal flowers numerous, their expanding lamina bluish

 whitish ; pappus of marginal flowers consisting of many

Fruits of the ray-flowers densely beset with a silk-like
