ovate or lanceolate few-toothed about the middle 3-nerved 
lower ones obtuse narrowed into petioles upper gradually 
smaller acute sessile rounded at the base, peduncles slender 
elongated erect with stellate down, involucre ovate at the base 
after flowering ventricose and constricted in the middle with 
scattered blackish hairs or setae, scales dark-green paler at the 
margin bluntish or subacute, ligules glabrous, styles livid. H. 
rigidum Koch. 
Banks, woods, and thickets, probably not uncommon. (No Scot- 
tish or Irish stations are mentioned by Mr. Backhouse.) If. 8, 9. 
— “ Stem occasionally forming small rosettes of leaves at or near the 
base, similar in appearance to those of the Pulmonarea, but not per- 
sistent during winter. Cauline leaves never clasping.” — Backhouse. 
The remaining species of this group never form persistent rosettes at 
the base of the stem. 
26. H. prenanthoides Vill. ( rough-bordered II.) ; stem erect 
hairy, panicle spreading leafy branched corymbose, leaves 
loosely reticulate and glaucous beneath denticulate or entire 
more or less hairy ciliate, lower ones oblong tapering into an 
aurieled amplexicaul petiole, upper ovate cordate acute or 
acuminate sessile, peduncles short floccose and involucre 
hispid with hairs and black setas, scales obtuse outer ones few 
and much smaller than the inner, ligules pilose at the apex.

River-sides in the Highlands of Scotland, Northumberland, and 
Yorkshire; rare. 11. 7,8 Heads small, numerous ; involucre cylin- 
drical, the scales placed somewhat in two rows, the outer considerably 
shorter than the inner, without an intermediate one : in bud the 
scales are inflexed. Styles yellowish or livid with minute dark hairs. 
Leaves gradually passing into bracteas, as in all this group. 
27. H. strictum Fries (straight-branched II.) ■ stem rigid 
b. Leaves glaucous beneath. Ligules pilose at the apex. 
26. H. prenanthoides Vill. ; leaves all amplexicaul loosely reticulated, heads in a 
corymbose panicle, peduncles short densely setose. 
27. H. striclutn Fries ; leaves 3 nerved lower narrowed to the base, heads irregu- 
larly corymbose, peduncles elongated with few or no seta'. 
c . Leaves green. Involucre not constricted. Ligules glabrous. 
* Scales of involucre reflexed at the point. Styles yellow. 
28. H. umbellalutn L. ; leaves loosely reticulated, peduncles not setose. 
** Scales of involucre adpressed. 
27. H. strictum Fr. ; leaves glaucous beneath 3-nerved, heads irregularly corym- 
bose, peduncles not scaly, styles with dark hairs. 
29. H. crocatum Fr. ; leaves green 3-nerved, heads subcorymbose, peduncles not 
scaly, styles with fuscous hairs. 
30. H. rigidum Fr. ; leaves paler or slightly glaucous beneath 3-nerved, heads 
in a branched leafy corymbose panicle, peduncles not scaly, styles with fus- 
cous hairs. 
31. H. corymbosum Fr. ; leaves glaucous beneath loosely reticulated, heads in a 
branched leafy corymbose panicle, peduncles scaly, styles yellow or with 
minute dark hairs. 
32. W.boreule Fr. ; leaves green 3-nerved, heads in a corymb or panicle, peduncles
