 laries are bent inwards, but do not meet together 

 in bud, rather broad, oblong, linear, narrow 

 above, blunt, the intermediate narrow, acute, 

 woolly-felted at the edge, hairy, glandular. The

 this plant is mountains and cliffs. The stem is 

 simple or branched, furrowed, slender, stiffly 

 hairy, woolly-felted above. The outer radical 

 leaves are oblong, rounded, blunt, heart-shaped, 

 the inner oblong, lance-shaped, oval, acute, blunt 

 or wedge-shaped, arrow-shaped below, toothed 

 below, the innermost narrower, acute, with a 

 long point, toothed, running down the leaf-stalk, 

 bluish-green, woolly-felted below, stiffly hairy on 

 the border. The stem-leaf low down is stalked, 

 narrow, linear, lance - shaped, sharply toothed. 

 The panicle is i -forked, the branches long and 

 curved. The stalks are woolly-felted, glandular. 

 The 4-7 heads are small, narrow, egg-shaped. 

 The phyllaries are narrow, greenish-black, ex- 

 tending forwards, woolly- felted, stiffly hairy, 

 glandular below. The ligules are hairless. The 

 styles are yellow. The pits of the receptacle 

 are cut, toothed. The plant is 6-14 in., flowering 

 in June and July, and is a herbaceous perennial. 



Golden Lungwort (Hieracium silvaticum, 

 Gouan). The habitat of this plant is woods and 

 dry places, rarely on walls, basaltic hills and 

 limestone rocks, mountain slopes. The stem is 

 smooth, or stiffly hairy, woolly-felted, glandular 

 above. The radical leaves are thin, membranous, 

 elliptic, lance-shaped, blunt or heart-shaped, 

 arrow-shaped below, toothed, the teeth horizontal 

 or bent back, stiffly hairy on the veins below. The 

 solitary stem-leaf is broad, linear, acute, toothed. 

 The panicle is corymbose, the lower branches 

 erect or spreading, ascending. The upper 

 branches are close, in an umbel, ascending, ex- 

 ceeding the acladium. The heads are cylindric, 

 egg-shaped, medium or small. The stalks are 

 glandular, woolly-felted, stiffly hairy. The phyl- 

 laries extend forwards, and are narrow, woolly- 

 felted, stiffly hairy, glandular. The ligules are 

 yellow or golden, smooth above, fringed with 

 hairs. The styles are livid or yellow. The mar- 

 gins of the receptacle pits are slightly raised, with 

 cut teeth, or shortly toothed. 



Hieracium aggregatum, Backh. The habitat of 

 this species is rocky streams, margins of alpine 

 streamlets. The stem is erect, reddish, woolly- 

 felted. The primary radical leaves are round, 

 the outer egg-shaped, oblong, elliptic, rounded, 

 pointed at the tip, blunt, narrow below, toothed, 

 the inner egg-shaped, lance-shaped, acute, toothed, 

 the leaf-base running down the stem, the inner- 

 most narrow, lance-shaped, acute, stiffly hairy 

 below. There is no stem-leaf or a small one, 

 linear or lance-shaped. The panicle is in a sort 

 of umbel, with 1-2 distant lower, erect, branches, 

 i-2-headed, the upper branches or stalks aggre- 

 gate (hence aggregatuni), spreading, ascending or 

 erect, exceeding the acladium. The stalks are 

 long, erect, woolly-felted. The 4-10 heads are 

 dark-green, rounded, egg-shaped. The phyl- 

 laries meet together in bud, and are awl-like, 

 lance-shaped, blunt, the inner linear, lance-shaped, 

 acute, with a pale border, woolly-felted, hairy, 

 glandular. The styles are yellow. The ligules 

 are smooth. The plant is 12-20 in. in height, 

 flowering in July and August, and is a herbaceous

Hieracium oxyodus, W. R. Linton. The stem 

 of this plant is slender, furrowed, purplish, stiffly

 dull-green, reddish-purple, the outer small, oval to 

 oblong, toothed, the inner oblong to lance-shaped, 

 acute, wedge-shaped below or narrower, toothed 

 below, stiffly hairy below and on the margins. 

 The stem-leaves are 1-2, the lower narrow, lance- 

 shaped, toothed below, narrowed to the winged 

 leaf-stalk, the upper bract-like. The panicle is 

 rather narrowed into a sort of umbel, with erect 

 lower branch, the branches erect, aggregate, in 

 a sort of umbel. The 4-7 or 20 heads are dark, 

 cylindric, egg-shaped, running down the stalk. 

 The stalks are woolly-felted, glandular, hairy. 

 The phyllaries meet together in bud, the outer 

 hairy, triangular, lance-shaped, the inner linear, 

 the innermost narrow, with broad, pale borders, 

 hairy, glandular. The ligules are stiffly hairy at 

 the tip. The styles are dull. 



Hieracium pellucidum, Lsestad. The radical 

 leaves of this plant are green with violet mark- 

 ings, transparent, with pin-holes, the outer 

 rounded, heart-shaped, blunt, the inner heart- 

 shaped, egg-shaped, the border finely toothed, the 

 teeth bent back, the innermost egg-shaped, lance- 

 shaped, with acute teeth. The stem-leaf is egg- 

 shaped, lance-shaped, entire or toothed below. 

 The panicle has one or two distant branches, the 

 upper close, spreading, bent inwards. The flower- 

 stalks are woolly-felted, glandular. The heads 

 are short, thick, with a round base. The phyl- 

 laries are short, broad, blunt, with a narrow, pale 

 border, senescent, glandular. The ligules are
