 Linn. Herb. The few British specimens seen are either much smaller, or when 

 larger, greenish-yellow, margins less regularly citrino-sorediate. A state of 

 Bhyscia jparwtina was often confounded with juniperinum by earlier writers and 

 even by some modern Hellenists, see Crombiein Journ. Bot. n. s. 1. p. 234.
