clothing of long, shaggy, hoary hairs, which become tawny by 

 keeping. These copious long hairs, and the large lemon-co- 

 loured^^^ott-ers, distinguish this species from every other of Bri- 

 tish growth. The seeds are chesnut-coloured, more angular 

 than striated, with a very smooth surface. Dowji rough, rather 

 short. 

 The figure in Engl. Dot. taken from an ill-chosen garden specimen, 

 is so unlike the wild plant, that I cannot wonder if Dr. Hooker 

 thought it a different species. Our H.villosum huH, however, 

 little affinity to H. Halleri of Villars, named hybrklum in his 

 t. 26; {DeCancL Fr. v. 4. 19. ffllld. v. 3. 1587,) and still less to 

 H. alpinum. This plant of Villars is, moreover, pumilum of 

 Willd.r. 3. 1562, under which name Mr. Sieber sent specimens 

 from Styria. It does not clearly appear from the FL Scot, whe- 

 ther this or villosum was gathered on Ben-y-more.

For a wild specimen of this I am also obliged to Mr. Robertson. 

 It agrees precisely with others sent from Styria, by Mr, Sieber, 

 and clears up every difficulty respecting this species and H. vil- 

 losum, from which, as well' as from H. alpinum, it is certainly 

 distinct ; though perhaps the latter is equally entitled to be 

 reckoned caulescent. The radical leaves of H. Halleri are much 

 fewer than in alpinum, less coarsely toothed, and one resembling 

 them is sometimes placed about an inch up the stem; one or 

 two still higher being very small, lanceolate, acute, and nearly 

 sessile. Stem usually simple and single-flowered, rarely 2- or 

 3-flowered, not shaggy, but rough with short, black, prominent 

 bristles, Cal. dark, clothed with some pale hairs, but by no 

 means shaggy like H. alpinum. The Jlorets however are exter- 

 nally hairy, about the summit of the tube, as in that species. 

 The whole^oit'er is of a full golden yellow, not lemon-coloured 

 like villosum; nor is the stem hollow as in that, but full of light 

 pith, exactly in the manner of H. alpinum.
