COMPOSITE. 187 
Radical leaves oval or oval-lanceolate, abruptly truncate or sub- 
cordate at the base, with rather short sparingly -woolly petioles, 
sub-obtuse (the outer ones obtuse), remotely repand-dcnticulate, 
or only callous-denticulate, sub-glabrous, ciliated with soft woolly 
hairs on the margins and midrib beneath ; stem generally leal- 
less, but sometimes with a small strapshaped bract-like leaf 
towards the base. Anthodcs moderately large, 2 to 5, in a corymb. 
Pericline truncate at the base ; phyllaries rather few, broad, sub- 
obtuse, dark-olive, sparingly clothed with stellate down and a few 
short black-based hairs and black gland-tipped hairs. Florets 
glabrous, not ciliated. Styles yellow. Plant intensely glaucous. 
On limestone rocks and debris at the foot of Giggleswick and 
Gordale Scars, near Settle, Yorkshire. 
England. Perennial. Summer and Autumn. 
Stem ascending or erect, 6 to 18 inches high, generally slightly 
curved in the lower part, and usually purplish-red. Primary 
haves very blunt, the lamina longer than the petiole and almost 
truncate at the base ; inner leaves more or less acute (when nu- 
merous, the inner ones quite acute), all very glaucous and 
blotched or speckled with purple. Peduncles rigid, ascending. 
Anthodes about the size of those of H. pallidum, and much resem- 
bling them. Achenes as large as those of H. pallidum, and very 
similar. 
Pries includes this species among his vulgata, on account of its 
hairs; but having cultivated for two years plants sent me by 
Mr. Tar ham, of Settle, I have no doubt Mr. Backhouse is right in 
placing it near H. pallidum, to some of the forms of which it 
approaches in habit, though the hairs on the leaves are rather softer, 
and the phyllaries much broader and obtuse at the apex.

Stem scape-like, corymbosely branched at the apex, fistulose, 
brous, the upper part and peduncles very sparingly clothed with 
stellate down and a few short hairs, and a very few black gland- 
tipped hairs. Radical leaves strapshaped-clliptical, very gradually 
attenuated into short broadly - winged very sparingly - woolly 
petioles, acute, remotely dentate or callous-denticulate in the 
middle, glabrous, often with scattered rather soft woolly hairs
