B. taraxacifolia DC. is a very variable plant. It may have one upright 

 stem or several almost prostrate ones. The leaves are almost entire, runcinate 

 or pinnatifid. Peduncles and involucral bracts are grey with stellate hairs and 

 often have black hairs as well, and these are sometimes glandular. Polymorphic. 



Grassy places, hill-sides, etc., very common. March-July. 



CREPIS L. HAWK'S-BEARD. 



C. bulbosa Cass. Root has long fibres ending in tubercles as large as a 

 nut, and also horizontal stolons throwing up leaves which are long petioled, 

 oblong-lanceolate entire or toothed, glabrous. Scape simple and i-headed, erect, 

 glandular at top. Flowers yellow. The rare Orobanche pubescens is parasitic 

 upon it. 



Sea-sands and occasionally in stony fields distant from the sea. April- 

 June. 



C. nicaeensis Balb. Annual. Stems 1-2^ ft. high, erect, branched, strongly 

 ridged, hispid below. Leaves pinnatifid and often runcinate ; lower ones 

 oblong, petioled, hairy, upper ones sessile, sagittate, flat. Heads larger than in 

 the common British C. vlrens. Involucre hairy-tomentose, the bracts glabrous 

 within. Achenes yellowish. Flowers yellow. 



Dry places, woods, and pastures in the hills. May-July. 



The following also occur on the littoral: C. pulchra L., C. virens L., 

 C. agrestis W. et K., and C. bfennis L. 



ANDRYALA L. 



A. integrifolia L. Annual, 1-2 ft. high, erect and branched covered with 

 yellowish-white tomentum. Leaves lanceolate, upper ones sessile, entire, en- 

 larged at the base ; lower ones toothed or sinuate, attenuate at base. Heads of 

 pale yellow flowers in a rather dense corymb. Peduncles and involucre glandu- 

 lar. Achenes brown, very small. Pappus reddish-white.

 Sub-genus I. STENOTHECA Fries. 



Involucre with bracts in 2 ranks, the outer ones very short, and resembling a

Sub-genus II. PILOSELLA Fries. 



Involucre of imbricated bracts ; achenes very small, slightly crenate at top ; 

 pappus hairs of equal length. 



H. Pilosella L. Mouse-ear Hawkweed. A small and variable species with 

 rooting stolons and spreading tufts of root-leaves. Leaves lanceolate, tapering 

 at base, usually white-tomentose beneath, and with long silky hairs. Stems 

 one headed, the flowers pale yellow, the outer ones often tinged with red. 

 Involucre covered with close, whitish down, and stiff, spreading, black

H. Peleterianum Merat, has shorter and thicker ascending stolons, and the 

 plant is more densely hairy and with larger flower heads than the last.
