Stem winged throughout. Radical leaves oblanceolate, blunt ; 

 stem-leaves decurrent, acute, both deeply sinuate-pinnatifid, spiny, 

 with scattered hairs above, more or less sparingly arachnoid beneath. 

 Anthodes aggregated at the summit of the stem, and branches 

 sub-sessile or very shortly stalked. Pericline cylindrical-ovoid, 

 glabrous ; phyllaries adpressed, strapshaped-lanceolate, acuminate, 

 shortly spinous-pointed, with the point curving outwards, the inner 

 ones as long as or longer than the florets. Pappus not plumose. 



In waste ground and by roadsides ; preferring sandy situations 

 and near the sea. Not uncommon in England and the South 

 of Scotland as far North as Eorfar and Fife. On the "West 

 coast it is not known to occur North of the neighbourhood of 

 Glasgow. 



England, Scotland, Ireland. Biennial. Annual. 

 Summer and Autumn. 



Stem erect, 6 inches to 4 feet high, branched in large examples, 

 with the branches making but a small angle with the stem. 

 Radical and lower leaves much attenuated towards the base, with 

 the terminal lobe transversely rhomboidal. Pericline f inch long 

 by \ broad ; inner phyllaries scarious at the edges. Flowers pale 

 pui'plish-pink. Achenes \ inch long, fawn-colour, shining, finely 

 transversely rugose, the disk with a very prominent tubercle in the 

 centre. Pappus much longer than the achene, pui-e white. Plant 

 green, more or less hoary. 



IMr. Bentham considers this plant identical with C. pycnocephalus 

 of Linnajus, a South European plant, which is probably distinct 

 from the present plant only as a sub-species. It ditlers in having 

 the heads larger, fewer together, on longer stalks, the pericline 

 oblong-ovoid, the florets longer in jiroportion to the scales, and 

 several other less obvious characters.
