40 Eucephalozia 



criminated. Hudson's y. multiflora is probably founded partly on DUlenius's de- 

 scription, for he does not appear to have seen the plant, and the only locality he cites 

 (Shooter's Hill) is that of DUlenius ; but Linnaeus's character (which he also cites) ' 

 "J. fronde repente ramosa, foholis altemis geminis setaceis sequalibus," Mant. H. 310, 

 points definitely to L. setacea alone. — Dillenius's tab. 70, f. 13, is represented in his 

 herbarium (according to Lindberg) by true C. cojinivens Dicks., having the autoicous 

 inflorescence and the other characters of that species ; but the figure looks more Uke 

 C. bicuspidata, and his specific phi'ase, "Lichenastrum pinnulis acutissime bifidis," 

 and the "foha Talde acute et profunde incisa" of his description, point to the same 

 species ; probably he had both plants under his eye (for they often grow intermixed) 

 and with his imperfect instruments they would certainly be undistinguishable.
