 Syn. Apargia Rosani, Ten. Stirpem Tenoreanam in regno Neapo- 

 litano nascentem nunquam vidi, hane tamen ex diagnosi Candol-

 Hetruria observavi, nullum dubito. 



This species is considerably larger in all its parts than L. Vil- 

 larsii, nevertheless it is doubtful whether the adpressed outer 

 scales of the involucre would afford a sufficient mark of specific 

 distinction, but, in the present state of our knowledge of this 

 group, we may assume that the roughness of the hairs with which 

 the leaves are abundantly clothed, together with the muricated 

 achenia, furnish characters which do not allow us to unite this 

 with the last-mentioned species.

There are no characters assigned to L. Berinii in the descrip- 

 tions of authors which justify its being retained as a distinct spe- 

 cies, and it is doubtful even whether it should rank as more than 

 a variety produced by the peculiar position in which it is found 

 in the sandy detritus of the rivers in Eriuli. 



The character of the pubescence is identical in both forms, but 

 it appears to be slightly shorter in the subsi)ecies arenarius. In 

 the ordinary form tlhe stellate hairs of the scape become gradually
