COMPOSITE? 147 



H. Auricula Lamk. Plant usually with stolons. Stem with a few small 

 flower heads. Leaves glaucous, in a rosette, lanceolate or obovate, with a few 

 silky hairs. Inner involucral bracts obtuse. 



Grassy places in the lower mountains. May-July. 



H. Sabinum Seb. Plant sometimes with stolons. Stems tall, covered 

 with stellate, simple and glandular hairs, bearing a cyme of rather numerous 

 heads. Leaves lanceolate, with long silky hairs on both sides. Closely allied 

 to H. cymosuiti L. which also occurs in many forms in the hills. June-August. 



H. praealtum Vill. A hawkweed without stolons. Leaves rather glauc- 

 ous, longer and narrower than in the last and with very few hairs. Flower 

 heads numerous, in a corymbiform panicle. Involucral bracts obtuse, covered, 

 like the peduncles with stellate and glandular hairs. 



Here and there on dry hill-sides and mountain slopes. June-August. 



H. florentinum All. A species closely allied to the last, but sometimes 

 with narrower leaves ; flower-heads smaller and in a looser panicle, the branches 

 arched and often rising from the middle of the stem ; peduncles with glandular 

 hairs but with few or no stellate ones (Bicknell). Intermediate forms occur. 



Beds of mountain torrents, etc., from the coast of les Alpes-Marit. and Liguria 

 to the mountains. May-July. 



Sub-genus III. ARCHIHIERACIUM Fr. 



Bracts of involucre imbricated; achenes larger than in sub-genus Pilosella, 

 not crenate ; pappus hairs of unequal length ; stronger than and not so white as 

 those of Pilosella. 



H. lanatum Vill. = H. tomentosum All. Plant about a foot high, 

 easily known by the felt-like appearance of the leaves, which are covered with a 

 short dense grey tomentum. Root-leaves ovate, acuminate, entire or obscurely 

 sinuate, stalked ; stem-leaves sessile, lanceolate amplexicaul. Involucral bracts 

 very woolly, lanceolate-acuminate. Stems bearing several large flower heads. 



Limestone rocks and cliffs in the lower mountains. June- August. 



H. andryaloides Vill. Differs from the last by its toothed leaves, its less 

 dense felt, its longer peduncles, its smaller heads and rather shorter stature. It 

 appears to be less rare in the Var than the last, which only occurs at the summit 

 of les Marges, but in the Maritime Alps this species is not so common. 



Rocks and cliffs in the hills and lower mountains. June-August. 



H. cinerascens Fr. Closely allied to H. pr^ecox Schultz Bipontinus 

 but of a more greyish colour. Leaves generally only slightly toothed, some- 

 what attenuated at the base and with silky hairs. Styles yellow. 



Hill-sides and woods. April, May. 



H. prtecox Schultz Bipontinus. Leaves very variable, generally with 

 large teeth or much incised at the base ; stem often bearing one petiolate leaf. 

 Flower heads rather large and numerous. Peduncles and involucral bracts very 

 glandular, style usually yellow. 



Woods and rocks, occasional. May-July. 



H. fragile Jord. Stems thick and fragile; petioles long and enlarged at 

 the base, leaves and petioles less hairy than in the last, of which this may be 

 merely a variable form. 



Woods and rocks. May-July. 



H. murorum L. Plant green or glaucous ; stem 1-2 ft. high, glabrous or 

 hairy below ; root-leaves in a rosette, ovate, acute, cordate or rounded at base, 

 entire or toothed ; stem-leaves o or very few. Heads 2-6. Peduncles floccose 

 and covered with simple and glandular hairs. Very variable. 



Woods and stony slopes, common. April-June.
