tance nearly parallel to the margins of the leaf. Anthodes about 

 the size of those of H. vulgatum. 



Prom the usual states of H. vulgatum, the absence of a rosette 

 and the numerous stem-leaves sufficiently distinguish it. It differs 

 from the more leafy forms in the anthodes being on longer and 

 more slender pedicels ; the pericline more abrupt at the base ; the 

 phyllaries broader and blunter, more glabrous, usually quite destitute 

 of gland-tipped hairs and stellate down, except sometimes at the 

 very base. 



From H. Gothicum, which it sometimes closely resembles, it 

 differs in being of a brighter green and more hairy, especially on the 

 lower part of the stem, petioles, and midribs of the leaves beneath. 

 The pedicels are more slender and shorter ; the anthodes much 

 smaller and more numerous ; the pericline less rounded at the 

 base ; the phyllaries paler and wi:^h more numerous hairs ; the 

 achenes smaller ; the pappus more tinged with brown : and the true 

 root-leaves, even when present in winter, always decay before spring.

Section III.— ACCIPITRHSTA. 



Rootstock not stoloniferous. Radical leaves none, the root- 

 stock producing a bud which develops into a leafy stem, but 

 never into a rosette ; stem with numerous leaves, the lower ones 

 withering before the flower expands. Phyllaries irregularly im- 

 bricated, or in 2 series with but few in the outer one. Achenes 

 rather large, not crenulated at the apex. Pappus of unequal 

 brittle rigid hairs. 



Gkoup a.— UMBELLATA. 



Stem leafy, without a basal rosette, umbellato-corymbosely 

 branched at the apex. Stem-leaves narrowed and not amplexicaul 

 at the base, paler (but not glaucous) beneath, and with the network 

 formed by the ultimate veins inconspicuous. Phyllaries numerous, 

 imbricated in several rows, sub-glabrous, destitute of gland-tipped 

 hairs, the outer ones squarrose at the tips. Achenes chestnut- 

 black when ripe.
