COMPOSITE. 181 



amplexicaul in var. 3 ; upper stem-leaf generally, but not always, 

 smaller than the lower one, commonly sessile, but sometimes 

 semi-amplexicaul. Anthodes large, generally 2 or 3 in number, 

 but varying from 1 to 6 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 H. nigrescens and the allied species, but generally with so many 

 white-tipped hairs that it appears greyer ; outermost phyllaries 

 small, rather lax. Plorets bright pale-yellow. Plant glaucous- 

 green, which will at once distinguish the black-headed states from 

 H. nigrescens and its allies of the Alpina group : amongst these 

 H. senescens bears the closest resemblance to H. 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 appear to me inseparable from each other, but 

 var. 7 (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 

 stellate 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 

 subpetiolate at the base ; upper ones amplexicaul, ovate-elliptical 

 or lanceolate, acuminate ; bracts at the base of the peduncles of the 

 corymb 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 witli 

 black-based hairs intermixed with a few short black gland-tipped
