HAB. Meadows and pastures, frequent, Light/. Ft. June. I/. 



Leaves radical, oblong, Lanceolate, more or less deeply toothed, some- 

 times almost pinnatifid, clothed with forked hairs. Flowers solitary, 

 upon a hairy scape, large, yellow, drooping before expansion. In- 

 volucre hairy. Sir J. E. Smith says that the hairs at the orifice of 

 each floret distinguish this plant from A. hirta, as well as from every 

 other species of the genus. 



2. A. hirta (deficient slpargia), scape single -flowered, leaves den- 

 tate scabrous, involucre nearly glabrous, outer pericarps with 

 a scaly pappus. E. B. t. 555. 



HAB. Gravelly pastures and moors about Glasg., occasionally - t moors 

 about Airdrie, Hopkirk. North Queensferry, Maughan. Fl. July, 

 Aug. -U 



This species was by Lightf. and many of the older botanists confound- 

 ed with the last, but is in reality very distinct from it : the flow- 

 ers are much smaller,, reddish beneath, and there is a great peculi- 

 arity in the outer seedvessels, they not having a pappus composed 

 of hair-like processes, but of small membranous scales. 



3. A. Taraxaci (alpine dpargia), scape single-flowered thick- 

 ened upwards, leaves glabrous runcinato-dentate, involucre 

 very hairy. Lightf. p. 435 (Hieracium Taraxaci). E. B. 

 t. 1109 (HedypnoisTarax.). 



HAB. Wet ground on the sides of the Highland mountains ; as on 

 Ben-na-Caillich in Strath- Swardle. Fl. July, Aug. 11 . 



Remarkable for its scape, which is thickened upwards, and having there, 

 like the involucre, blackish hairs. Flowers rather large, yellow. 



4. A. auiumnalis (atumnal Jlpargia), scape branched scaly up- 

 wards, leaves lanceolate toothed or pinnatifid subglabrous, pe- 

 duncles swelling beneath the involucre. Lightf. p. 433 (Leon- 

 todon autumnale), E. B, t. 830 (Hedypnois autumn.). 



HAB. Meadows and pastures, frequent. Fl. Aug. 14 . 

 Involucre cylindrical, and tapering down gradually into the scape. 

 Flowers rather large, yellow. 



8. HIERACIUM. 

 * Scape naked (or rawly with one leaf), single-flowered. 



1. H. alpinum (alpine Haivkweed), scape 1 -flowered leaflets 

 hairy, as well as the oblongo-lanceolate entire leaves, involucre 

 thickly clothed all over with long silky hairs. Lightf. p. 434. 

 t. 18. JB.B.M110. 



HAB. Dry soil near the summits of the Highland mountains, as in 

 Breadalbane and Glenco, Dr. Stuart. In Ross-shire and in Skye, 

 Lightf. On Ben Arthur, opposite Arroquhar, Mr. Borrer and 

 Hook. Fl. July,. Aug. I/. 



Four to six inches high. Leaves with numerous whitish hairs, especi- 

 ally at the base, which is lengthened into a petiole. Hairs on 

 the upper part of the stem black at the base, and often mixed
