included; filaments filiform-subulate; anthers linear, rounded or 
emarginate at the apex, cordate at the base, the lobes rounded. 
Style filiform. Stigmas filiform, usually longer than the style. 
Achene fusiform, 10-12-ribbed, pubescent. Pappus of numerous 
capillary barbellate bristles, longer than the achenes.—(Generic 
name Greek, meaning sand-torch, referring to the habitat and 
the blazing rose- -purple flower-heads .) 
The white sands of the inland dunes are an excellent back- 
ground for showing off the various plants that arise from the 
desert-like surface from season to season. This is one of the 
more conspicuous plants of the summer months, chiefly on 
account of its bright rose-purple flower-heads. 
This showy plant is confined strictly to the dry sands of the 
“scrub.” It is well adapted to maintain itself there by a large 
storage root. Ammopursas is related to Laciniaria, from which 
it differs in the succulent foliage, the open inflorescence, the 
somewhat zygomorphic corollas with inflated throats, and the 
short pappus. As a genus it is on a par with Garberia and 
Carphephorus.
