cies, formed of about two hair-like concentric 

 circL's. 



Such .^rc cur fpecimens, and fuch are'thofe of A'/- 

 tenius wl'iich we compar'd with ours. 



Ir differs fiom the brccedino; in the Imallnefs of 

 the tubercles, and in having no rigid hairs ori 

 the margin, otherv/ife in colour and fubftancc 

 it is veiy like it, and we fufpecl it to be only a 

 variery, as the margins of the leaves in rhat dd 

 cfteii produce but very few hairs, and therefore 

 may ptrhai;s be found foinetimes bald, or en- 

 tirely wiiiiout ilai^s. 



It may be alio readily diftinguiflied from the L. 

 mi'/iuilus btl ore-mentioned, not only by its 

 black-gn:y colour, but alfd in having fmall 

 elevated black hair-bufton tubercles-, whereas 

 the other has ordy innumerable fine imprels'd 

 dots or |:oir;ts.
