margins. This grows in the Ix)wer TemperAte life zone in South- 

 eastern Utah. 



E. corymbosum var. glutinosum (Jones Cont. 7 719) E. 



aureuin Jones and its varieties. 



This is an intricately branched form of E. coryml»osum witli 

 smaller involucres and golden yellow flowers; the pubescence be- 

 ing mucli denser and the inflorescnce still more reduced and very 

 short peduncled; the leaves in the type are broadly elliptical and 

 nearly sessile, but they vary to narrowly oblong and crimped, with 

 the flowers rather racemose on the upper side of the branches after 

 the fashion of E. Jonesii. This approaches E. sulcatum in habit. 

 The varieties ambigiuim and glutiivosum are only variant forms 

 not worthy of varietal rank.
