 oblong- to linear-lanceolate, the lowest tapering into margined petioles ; ra- 

 cemes numerous, commonly geminate and in fruit rather strict ; corolla larger 

 (blue, sometimes white), 2-3" in diameter; nutlets scabrous and margined 

 with a close row of flat subulate prickles- Minn, and Sask., and westward. 

 * # Racemes leafy-bracteate . stout pedicels not deflexed ,- calyx becoming foli- 



aceous ; leaves linear, lanceolate, or the lower spatulate ; hispid annuals. 



E. LAPPULA, Lehm. Erect, 1-2 high, nutlets rough-granulate or tuber-

 the base upward. Ours are very hispid annuals or biennials, with small 

 white flowers in scorpioid spikes. A large western genus. (Dedicated to 

 Prof. J. Krynitzki, of Cracow.) 



1. K. crassisepala, Gray. Annual, diffusely much branched, a span 

 high, very rough-hispid ; leaves oblanceolate and linear-spatulate ; flowers very 

 small, short-pedicelled, mostly bracteate ; lobes of the persistent calyx closed 

 over the fruit y the midrib below becoming much thickened and indurated; nutlets 

 ovate, acute, dissimilar, 3 of them muricate-granulate and 1 larger and smooth,
