about 2.5 cm. long on the stems, less than half as long and re- 

 curving on the branches, puberulent: heads cymose-fascicled, 

 crowded : bracts of the viscidly lucid involucre narrowly lanceo- 

 late, abruptly produced into a spreading setiform tip or short 

 awn, or the much shorter outermost ones muticous. 



Collected only by Dr. Heermann, somewhere near Tejon Pass. 

 In the absence of specimens the above description is as given by

Low shrub with the branches densely and permanently white- 

 tomentose and the leaves loosely white-tomentose in the typical

 acute, keeled by the strong nerve, imbricated in indistinctly ver-

 the tube arachnoid-pubescent : style-appendages subulate-filiform, 

 longer than the stigmatic portion : pappus soft.
