" In the appendix (p. 659) to the reprint to the 2nd Ed. of 

 the Flora Anglica, Lichen flavo-rubescens is acknowledged to 

 be the same as Lightfoot's Lichen aurantiacus. That work 

 preceded Hudson's 2nd Ed., but not his first ; so why he 

 relinquished the name is not quite clear, but from several 

 instances it is evident that Hudson was no stickler for 

 mere names" — (J. A.M.)
