COMPOSITE. 1 8 L 
unplexicaul in var. 3 ; upper stem-leaf generally, but not always, 
smaller than the lower one, commonly sessile, but sometimes 
Bemi-amplexicaul. Anthodes large, generally 2 or 3 in number, 
but varying from 1 to G or more in the cultivated plant. Peduncles 
arching upwards, with stellate down and very numerous short black 
gland-tipped hairs. Pericline dark, sometimes nearly as black as 
in II. nigrescens and the allied species, but generally with so many 
white-tipped hairs that it appears greyer ; outermost phyllaries 
small, rather lax. Florets bright pale-yellow. Plant glaucous- 
green, which will at once distinguish the black-headed states from 
11. nigrescens and its allies of the Alpina group : amongst these 
1 1 . senescens bears the closest resemblance to II. Anglicum, but 
the latter has the stem more leafy, the radical leaves larger in pro- 
portion, with more woolly peduncles, the florets with fewer hairs 
on the back, the pericline larger and more enlarged at the base, 
and the phyllaries more numerous. 
Vars. a and 3 aj^pear to me inseparable from each other, but 
var. y (acutifolium) looks very different, on account of its some- 
what oblong sharply-toothed leaves. ;

Stem corymbosely branched at the apex, sparingly clothed 
with simple white hairs, the upper part and peduncles with 
itellate down, black-based hairs, and a few black gland-tipped 
hairs. Radical leaves oval or elliptical, gradually contracted into 
rather short or short broadly - winged densely - woolly petioles, 
acute, dentate or denticulate (especially near the middle) on the 
margins, sparingly clothed with simple hairs beneath or on both 
sides ; stem-leaves 3 to 7, the lower ones attenuated and often 
rabpetiolate at the base; upper ones amplexicaul, ovate-elliptical 
or lanceolate, acuminate ; bracts at the base of the peduncles of the 
ymb lanceolate or strapshaped. Anthodes large, generally 4 or 
5 in a terminal corymb. Pericline truncate at the base ; phyllaries 
numerous, acuminate, adpressed, olive, sparingly clothed with 
black-based hairs intermixed with a few short black gland-tipped
