2-3 dm. high as opposed to plants of a meter or so in height, onthe: 
ably looser growth, and mostly herbaceous character. In E. Squiresit 
and £. elatum the upper surface of the leaves is distinctly though 
sparingly puberulent. In E. tovarense the leaves are lanceolate not 
oblanceolate and are strikingly glandular-atomiferous beneath. £. 
turbacense is said to attain 2 m. in height. Tt has lanceolate to ovate _ 
leaves 5-7 cm. wide, and its involucre is more campanulate and has 
the scales usually 3-4-costulate. The florets are also somewhat more 
numerous, 25-28. 
It is clear that EZ. Sprucei cannot at present be united with mya 
these, yet they are all exceedingly close and may sometime be fo 
to intergrade. -
