About hedges and in dry waste ground, not very common. 



Annual. June, July. 



Root long and tapering. Stem about a yard high, much branched, 

 with copious, wavy, continuous, spinous wings. Herbage green, 

 .scarcely at all downy, icawesdeeply pinnatifidand sinuated, green 

 on both sides, very spinous, decurrent ; radical ones stalked. 

 Fl. crowded at the tops of the branches, purplish-crimson, not 

 half the size of the last, being hardly an inch broad. Cal. very 

 slightly downy ; its scales narrow, evidently spinous, some of 

 the inner ones recurved at the tips, especially at an advanced 

 period. Anth. imperfect in some flowers, stigma in others. Seed- 

 down minutely rough. 



This species, before the herbarium of Linnasus came to England, 

 wras generally taken for his crispus, but the leaves of the latter 

 are white, and mostly cottony, underneath ; its calyx-scales 

 more leafy and erect, the inner ones coloured. This latter, n. 165 

 of Haller, who wrongly quotes J. Bauhin, is a stranger in Bri- 

 tain, as our acanthoides appears to be in Switzerland. 



3. C, tenuiflorus. Slender-flowered Thistle. 



Leaves decurrent, sinuated, spinous. Flowers aggregate, 



sessile. Calyx nearly cylindrical; scales ovate at the 



base ; somewhat recurved at the point.
