 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 charactei's 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 retamed as a distinct spe- 

 cies, and it is doubtful even whether it should rank as moi'e than 

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

 in the sandy detritus of the rivers in Friuli. 



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

 it appears to be slightly shorter in the subspecies arenarius. In 

 the ordinary form the stellate hairs of the scape become gradually
