including the rays which are very many and narrow, 3" 

 long, purple; bracts green but sparsely hispid; lower 

 leaves pinnatifid with distant linear lobes; leaves oblance- 

 olate-linear, on long petioles; upper leaves sessile, linear, 

 20" long; flowers corymbose above, heads long-pedun- 

 cled, with gradually reduced, bract -like leaves on the 

 peduncles; plants erect, 9-18' high, growing in clumps 

 in the crevices of hot sandstone rocks in the most exposed 

 situations. I also refer to this a plant collected by Vasey 

 in 1881 in California, and by Dr. Smart on the Verde 

 River, Arizona, in 1867, both being referred to E . diver- 

 gens and both being barely woody at base.
