186 ENGLISH BOTANY. 



small, 2 to 6, in a corymb. Pericline hemispherical at the base ; 

 phyllaries rather few, acute, dark-olive, with copious stellate down 

 and a few long simple white or black-based hairs, and a small 

 number of black gland-tipped hairs. Plorets glabrous, not ciliated. 

 Styles yellow. Plant ash-colour. 



" In heathy alpine glens, at an elevation of 1,000 to 2,500 feet. 

 Hare. Near Llyn Ogwen, Carnarvonshire ; Craig-Breidden, Mont- 

 gomeryshire ; Glen Dole and ravine of the White Water, Clova 

 Mountains, Eorfarshire ; near Castleton of Braemar, ravine de- 

 scending from Ben-na-bourd, and Little Craigindal, Aberdeenshire" 

 (Back. I.e.) ; " Bocks at Bonas Voe, Shetland (Mr. Tate) ; Ben 

 Bulben Sligo ; and cliffs south of Glenarm " (Dr. Dickie). 



England, Scotland, Ireland. Perennial. Autumn. 



Stem 8 to 20 inches high, rigid. Badical leaves rounded at the 

 base, the inner ones generally acute, the outer very blunt, often 

 whitish below, from the abundance of stellate pubescence. Anthodes 

 considerably smaller than those of H. pallidum. Leaves generally 

 with long bulbous-based hairs on both sides and on the margin. 

 Pericline greyish, from the abundance of white stellate down. 



This species I have never collected, and of it I have seen but 

 few specimens ; but it seems quite distinct from H. pallidum, having 

 more the habit of H. murorum, but differing from it in the harsh 

 bulbous-based hairs, grey leaves clothed with copious stellate down, 

 and the yellow styles. 



H. lasiophyllum (Koch) is unknown to me except by description, 

 and neither Mr. Backhouse nor Professor Babington appears to 

 have seen authentic specimens. Pries, on the other hand, who 

 has cultivated the H. lasiophyllum from seeds sent him by Koch, 

 considers it distinct from H. cinerescens. All the authors quoted 

 above agree that our plant is the H. cinerescens of Jordan, and it 

 is identical with specimens I have received under that name from 

 Piedmont {Rostan), Dauphine (Gariocl), but quite different from a 

 plant from Lyons (Jlartm), though the nomenclature of the last 

 is affirmed to be authenticated by M. Jordan himself.
