 The stem has long, soft hairs, woolly felt, and 

 glands above. The radical leaves are inversely 

 egg- shaped, spoon-shaped, ben.t back above, 

 blunt, narrowed to the leaf-stalk, entire or slightly 

 toothed, sparingly stiffly hairy above, with bulbous- 

 based hairs below and on the margins. The stem- 

 leaf is lance-shaped or strap-shaped, the upper 

 ones bract-like. The heads are large, rounded 

 below. The dark phyllaries are broad, the outer 

 loose, acute, the inner linear, lance-shaped, with 

 a long, narrow point, the innermost with a bristle- 

 like point, with hairs and glands. The ligules are

 granite. The plant is green, the stem i-headed, 

 woolly -felted, shaggy, glandular. The radical 

 leaves are yellowish, lance-shaped or inversely so, 

 acute, narrowed to the leaf-stalk, entire or toothed, 

 cut, with sharp acute teeth, with blunt points, 

 hairy both sides. The leaf- stalks are broadly 

 winged. The stem-leaves are single or absent, 

 or 2-3, linear, lance-shaped. The solitary heads, 

 or 2 or more, are rounded, bell -shaped. The 

 outer phyllaries are loose, short, blunt, the inner 

 linear, with a long narrow point, or narrow acute, 

 with shaggy hair and glands. The ligules are 

 stiffly hairy. The styles are dark-livid or black. 

 The plant is 6-15 in. high, flowering in July and

Hieracium calenduliflorum, Backh. The habi- 

 tat of this plant is lofty mountains, grassy slopes, 



and rocky ledges. The plant is dark-green, the 

 stem is stout, woolly-felted, shaggy, and glandu- 

 lar. The radical leaves are elliptic, inversely 

 egg-shaped, blunt, entire, lance-shaped, toothed, 

 abruptly narrowed to the leaf-stalk, the inner 

 narrower, acute, with acute teeth below. The 

 1-2 stem-leaves are usually bract-like. The 1-3 

 heads (usually i) are large, rounded below, long- 

 stalked. The outer phyllaries are lance-shaped, 

 blunt, loose, the inner linear with a long* narrow 

 point, acute, shaggy. The ligules are stiffly hairy. 

 The styles are very dark. The pits of the recep- 

 tacle have raised borders, shortly-toothed, with a 

 margin of hairs. The plant is 6-14 in. in height, 

 flowering in July and August, and is a herbaceous 

 perennial. 



Hieracium gracilentum, Backh. The habitat of

 rocky ledges. It ascends to 1200 metres in Ross, 

 Banff, Aberdeen, Perth, Inverness, Argyll. The 

 stem is woolly-felted, glandular, hairy. The radical 

 leaves are bright -green, inversely egg-shaped,
