This generally confifts of a fmgle leaf, about an 

 inch in diameter, deeply laciniated ; or of fe- 

 veral leaves, united together by an umbilical 

 cord in the centre, on the under fide. Their 

 fubftance is fllff, and like parchment, and their 

 edges fringed or ciliated, more or lefs, with fim- 

 ple and branched rigid hairs, of a blackidi co- 

 lour. Their upper fide is of a black grey co- 

 lour, a little concave, the margins being ele- 

 vated. The under fide is fmooth, buff-colour'd 

 about the centre, but of a black or fmoky grey 

 colour about the margins. 



The pelt^., or Ihields, are black, fupported on 

 very fliort peduncles, and curioufly form'd. 

 They are about the fize of a pin's head, their 

 furface fometimes plain, and fometimes convex, 

 appearing as if compofed of a horfe-hair, laid 

 fomietimes in concentric circles, and other times 

 in curled fpirals, fo as to refemble, according to 

 Dilienius, a horfe-hair button.
