Elevated rocky mountains. If.. 7, 8. — Stem usually simple, but 

 often becoming branched when cultivated. Leaves deeply toothed some- 

 times almost laciniate. The involucre diflers slightly in form from 

 that of the last species, and its scales are narrower, more uniform in 

 appearance, and usually clothed with more copious black seta\ 



9. 11, nigrescens\^\Vidi, (hlack-Jicaded H.) ; green, stem with 

 one or few heads usually with one leaf, leaves ovate or lanceo- 

 late sinuate-toothed at the base, heads in bud erect, peduncles 

 and involucre stellate-downy black with seta? mixed with grey 

 pointed hairs, scales broad outer ones bluntish, inner acuminate 

 much longer than the opening florets, ligules ciliated, styles 

 livid. H. pulmonarium Sm. : F. B. t. 2307. 



Clova and Aberdeenshire mountains. 1/.. 7, 8. — Distinguished 

 from the last by the broader leaves and copious grey starry pubescence 

 on the peduncles.

 inner lanceolate tapering at both ends irregularly toothed 

 towards the base, petioles shaggy, cauline usually one small 

 and narrow, summit of peduncle and urceolate involucre clothed 

 with black setas and whitish hairs mixed with glarry down,

Striden-edge, Plelvellyn, Westmoreland, Clova and Braemar 

 mountains. IX. 7, 8. — Hairs on the leaves and their stalks con- 

 spicuously denticulate, as in most other British species with shaggy 

 petioles, but in no degree plumose. We are by no means satisfied 

 that this is distinct from the last species, with which we formerly 

 ' combined it; we see no difference of colour in the styles in our dried 

 specimens. Mr. Backhouse remarks to us that "■' 11. nigrescens has 

 acuminate or obtuse broad phyllaries (involucral scales), and //. 

 chrysanthum linear or attenuate and acute ones, with very irregularly 

 toothed leaves and usually nodding flowers." We are indebted for the 

 synonyms to this species to Mr. Backhouse, who adds that the true 

 H. atratum of Fries does not appear to have been yet found in this 

 country.
