Stem leafy, corynibosely or paniculato-corymboscly branched 
at the apex, sparingly hairy with simple woolly hairs below, sub- 
glabrous in the middle, puberulent with stellate down on the 
upper part and peduncles ; the latter with a few black-based hairs, 
but few or no gland-tipped hairs. Radical leaves always decayed 
by the time of flowering, but sometimes there is a small lateral tuft 
which simulates a radical rosette ; lowest leaves elliptical-oblan- 
ceolate, petiolate; intermediate ones elliptical, attenuated at both 
ends; uppermost ones sessile, not amplexicaul, lanceolate, attenu- 
ated towards the apex, acute, all more or less strongly serrate 
towards the middle, with the teeth very distant and elongated, 
entire at the apex, sub-glabrous above, generally slightly hairy 
beneath and on the margins, woolly on the midrib beneath as well 
as on the petioles of the leaves. Anthodes rather small, usually 
numerous, in a corymb or corymbose-topped panicle, on straight 
rather short slender erect or ascending pedicels. Pericline trun- 
cate at the base, conical after flowering ; phyllaries numerous, sub- 
obtuse, inner ones narrower, olive, nearly glabrous, with a few short 
simple black or white-tipped hairs mostly along the middle line, 
occasionally with a few gland-tipped hairs and sometimes a little 
stellate down towards the base. Elorets glabrous, not ciliated 
towards the apex. Styles livid. 
In hedgebanks and margins of woods. Rather common, and 
generally distributed in England ; apparently rare in Scotland, 
uhere I have never gathered it; but Professor Babington gives it 
as occurring both in Scotland and Ireland. Mr. H. C. Watson 
doubts its existence in Scotland. 
England, Scotland (?), Ireland. Perennial. Autumn. 
Stem erect, slightly flexuous, 18 inches to 5 feet high, usually 
distinctly hairy below. Leaves much resembling the stem-leaves 
of IE. vulgatum, but more strongly toothed towards the middle and 
with the lateral veins curving round more, so as to run for some dis-
