reduced to spines of the broad rachis : heads sessile or subsessile 

 among the upper leaves : involucre about 4 cm. high ; the bracts 

 very unequal, imbricated, lanceolate-acuminate, terminating in a 

 short spine and spinosely ciliate above the middle, straight and 

 erect or ascending, cobwebby-pubescent: corolla-lobes broad- 

 linear, acutish : anther-tips acute. 



In saline soil near the coast of Santa Barbara Co. at Surf. 

 Elmer, no. 3631. The only specimen I have seen is the type, 

 preserved at the Stanford University Herbarium. A similar spe- 

 cies, or perhaps only a form of this, has been gathered at Santa 

 Maria by Miss Eastwood, whose specimens were unfortunately de- 

 stroyed in the San Francisco fire. As I remember them they 

 were much greener than Elmer's type, being nearly destitute of 

 tomentum, and with more nearly equal bracts.
