Seed angled. Pappus hairy. 
This plant appears to me to differ very much from the E. Coelestinum with 
which it has usually been confounded 5 it is a more slender plant, its leaves 
are thinner and more glabrous, the corymbs less compact, the scales of the 
involucrum less numerous but larger, the style comparatively shorter. It 
is probably the plant of Petiver alluded to by Dillenius, Hort. Elth. p 
140. 
Grows in loose rich soils. 
Flowers October to November.
