27. eiRSIUM EllIOPHORUM. [CL. XIX. 



so deeply semi-pinnate, run down the stem. The stem itself 

 is not so tall, and the flowers are not so large as in our spe- 

 pies. Cnicus laniflorus M. B. js still more nearly related to 

 it, and is distinguished by having the scales of its calyx 

 jbroader ;— these are of a reddish colour. As this corresponds 

 with the figure in the Engl. Bot, it becomes a question, 

 whether the Tauric and British plants be not the same 

 variety of C. eriophorum^ The other species have a less 

 perfect resemblance. Cirsium, long ago very correctly dis- 

 tinguished by Tournefort, has been named Cnicus by some 

 Jater writers, who have not recollected, that Seb. Vaillant a 

 century ago, had given the name to the well marked Centath 

 rea henedicta as a peculiar gen^is. We appropriate the name 

 Cirsium, therefore, to those thistles the pappi of which are 

 pinnate and the scales of the calyx thorny. If the scales of 

 the calyx are unarmed, it is the genus Saussurea De Candy 

 If the pappus is simply hairy, it is the genus Carduus.

Geographical Distribution. 



In England, where this thistle is not rare, its farthest nor- 

 thern limit is Cumberland*, (between 54° and 55° N. Lat.) 

 In Germany, again, it extends only a little beyond 51° ; but 

 southward from this, it is very common in all hilly regions, 

 especially in the Palatinate, Austria, Hungary, Transylvania. 

 If GiHibert's account (Jundzill, Fl. Lithuan. 244.) be correct, 

 it grows again more eastward, as far as 55°, for it is found be- 



* It grows also in Scotland, but sparingly ; as near the foot of Largo Law 

 in jFifcshire.
