170 ENGLISH BOTANY. 



Stem always simple, densely clothed with long soft black- 

 based hairs, and sparingly with stellate down, occasionally inter- 

 mixed with a few short black gland-tipped hairs. Radical leaves 

 oblanceolate or oblong-oblanceolate, gradually attenuated into the 

 petiole, blunt, entire ; the inner ones narrower, sub-acute, and 

 sometimes sparingly and remotely dentate-serrate ; stem-leaves 1 

 or 2, small, linear oblanceolate or strapshaped, sometimes absent, 

 all sparingly clothed with long woolly hairs on both sides. An- 

 thodes solitary both in the wild and cultiv^tted state. Pericline 

 turbinate, narrowed at the base. Inner phyllaries adpressed, acute ; 

 outer ones lax, broad, obtuse ; all olive-black, very densely clothed 

 with very long silky-woolly black-based hairs. Plorets hairy 

 externally and at the tips. Styles bright yellow. 



Alpine cliffs at an elevation of 2,000 to 3,500 feet. Glen- 

 amara, Langdale Pikes, and head of Pierce Gill, Scaw-fell, Cum- 

 berland, on slate. Loch-na-gar and Craig Dhuloch, Aberdeen- 

 shire, on granite. ClifPs of Caness, Canlochen Glen, and to the 

 south of Bradoonie, Clova Mountains, Porfarshire, and Ben 

 Lawers, Perthshire, on mica-slate (Backhouse). I have myself 

 only gathered it on Loch-na-gar. Mr. H. C. Watson has it from 

 the north of the Sow of Atholl and Ben Nevis. 



Scotland. Perennial. Autumn. 



Stem 3 to 10 inches high, and, as well as the anthode, much 

 more thickly clothed with long silky wool than in any of the other 

 species of this group, indeed, of any that have been indicated in 

 Britain, except H. villosum. Leaves not so yellow a green, and (if 

 my memory does not deceive me) slightly glaucous, narrower, 

 blunter, and more gradually attenuated into the petiole, than in 

 H. eximium, and almost always quite entire. The outer phyllaries 

 are commonly broad, and frequently subfoliaceous. 



In cultivation Mr. Backhouse states it becomes still more dwarf 

 and shaggy, and the stem never produces more than one head.
