328 THE COMPOSITE FAMILY. 



Achenes narrowed into a distinct, slender beak (Barkhausia) . 



All the achenes with a long, slender beak. Outer involucral bracts 



lanceolate, whitish at the edges 1. Seaked C. 



Achenes of the outer florets scarcely beaked, the others with a long 



beak. Outer involucral bracts small, and very narrow ... 2. Fetid C. 

 Achenes contracted at the top, but without a distinct beak. 

 Lower leaves piunatifid, or very narrow. Flower-heads numerous. 

 Pappus very white, and silky. 



Outer bracts of the involucre narrow-linear 3. Smooth C. 



Outer bracts of the involucre oblong-linear, with a whitish edge . 4. Hough C. 

 Leaves mostly oblong, coarsely toothed or entire. Flower-heads 

 few. Pappus not very white, and rather stitF. 

 Leaves mostly entire. Achenes with about 20 ribs or strise . . . 5. Saickweed C. 

 Leaves mostly toothed. Achenes with 10 ribs or strise .... 6. jtiursh C. 



The pink HatvTcweed, forruerly much cultivated in flower-gardens, is a 

 species of Crepis from south-eastern Eiu-ope; the bristly Crepis (C. setosa, 

 Eng. Bot. Siippl. t. 2945), which has the long-beaked achenes of the 

 heaJced C, but is covered with stiff, spreading hairs, is a south-east Euro- 

 pean plant, which has occasionally appeared in Britain as a weed of cul-- 

 tivation. 



1. Beaked Crepis. Crepis taraxacifolia, ThuU. 

 (Eng. Bot. Suppl. t. 2929. Borckhausia, Brit. Fl.) 



Much resembles some forms of the rough C, but easily known by the 

 pappus. Leaves chiefly radical and pinnatifid, with a large, terminal, 

 coarsely toothed lobe, and small ones along the stalk. Stems erect, 1 to 2 

 feet high, bearing a few small, narrow leaves. Flower-heads smaller than 

 in the fetid C, forming a loose, terminal, flat corymb. Involucres scarcely 

 hairy, tlie otiter bracts much shorter than the inner ones, lanceolate, and 

 more or less membranous and whitish on the edges. Achenes all termi- 

 nated by a slender beak about the length of the achene itself. 



In rather dry pastures, and waste places, in central and especially southern 

 Europe, and eastward to the Caucasus, not extending into northern Ger- 

 many. In Britain, chiefly in limestone districts of southern England and 

 Ireland ; rather more frequent than the Jetid C, but appears to have been 

 frequently confounded with that plant or with the rough C. Fl. summer. 



2. Fetid Crepis. Crepis foetida, Linn. 

 (Eng. Bot. t. 406. Borckhausia, Brit. Fl.) 



A slightly hairy annual or biennial, seldom a foot high, with a few spread- 

 ing branches. Radical leaves irregularly pinnatifid, with short lobes, the 

 terminal one varying from broadly triangular to narrow-oblong ; the stem- 

 leaves narrow, the lower slightly pinnatifid, the upper entire or toothed. 

 Flower-heads few, on long peduncles, usually recurved after flowering. In- 

 volucres hairy, the outer bracts small, and very narrow. The beak of the 

 outer achenes is very short, often scarcely distinct, wliilst that of the inner 

 ones is long and slender, carrying up the whole pappus above the tijjs of 

 the involucral bracts. 



In rather dry pastures, and waste places, in southern Europe to the Cau- 

 casus, becomes rare further north. In Britain only in some of the southern 

 and eastern counties of England. Fl. summer. 



3. Smooth Crepis. Crepis virens, Linn. 

 (C. tectorum, Eng. Bot. t. 1111.) 

 An erect or ascending, branched annual or biennial, from 1 to 3 feet'
