E. Marrubium ? Walt. p. 199-

triplinerved, dotted, slightly scabrous, with a somewhat glaucous or per- 
haps more correctly hoary hue. Flowers in a fastigiate corymb. Involu - 
erum ten-leaved, five-flowered ; leaves lanceolate, acute, very pubescent. 
Corolla white. Stamens very short. Style much longer than the corolla. 
Seeds angled. Pappus scabrous, longer than the corolla. 
Decoctions of this as well as of the preceding species are used with much 
success as a tonic febrifuge.

Grows in dry pine barrens. 
Flowers from July to September,
