 into alternate small foliaceous lanceolate bracts. Capitula large, 

 2 inches in diameter, bright blue. Involucres of many imbri- 

 cated, linear, green, erect scales, the lower ones tinged with 

 brown ; the outermost short and subpatent. Florets all ligu- 

 late ; central ones bilabiate, inner lip small, bipartite, the seg- 

 ments spirally twisted. Anthers exserted, deep purple; branches 

 of the style linear, recurved, dilated at the apex, grooved above, 

 the margin glandularly pubescent.
