 branched from the base : leaves oblong-lanceolate or spatulate, 2 to 5 lines long and 

 with slender petiole of equal length : flowers 3 to 7", scattered in a filiform loose 

 raceme, the primary one scapiform ; pedicels spreading : corolla about half the

Northwestern Nevada, Watson (young specimens, taken for a state of Pliacelia pusilla), also 

 Zemmon. Calyx in lilossom one line, in fruit 2 lines long. Corolla apparently white, persistent,

6. E. penduliflora, Benth. A span to a foot high, villous-pubescent, some- 

 what viscid: leaves pinnatilid; the lobes numerous, short, somewhat toothed or 

 incised : pedicels filiform, at base sometimes bracted, as lung as the at length nod- 

 ding flowers : filaments almost free from the broadly campanulate unwithering 

 corolla : ovules about 1G. 



Open ground, not rare from Lake Co. to San Diego, extending cast to Southern Utah. Flowers 

 handsome : corolla almost half an inch long. Seeds a line long. 



7. CONANTHUS, S. Watson. 



Calyx deeply 5-parted, the lobes very narrow and similar. Corolla funnclform,
