Saffron Lichen, with flat lliields. 



We are indebted to Mr, Stuart for the difcovery of 

 this rare Lichen, who found it upon a rock near 

 the top of Bentejkerney^ in Breaclalbane. 



The leaves are about an inch long, and a thumb's 

 breadth, dilated towards the extremity, and 

 f5ightly divided into obtufe lobes. They grow 

 three or four together, and Ipread flat upon the 

 ground, fometimes ir^ a circular form^ but com- 

 monly in no regular order. The upper furface 

 is of a whitifh green, the lower one a fine faf- 

 fron or orange colour, diftinguiflied alfo by hav- 

 ing downy fweliing branched veins, of the fame; 

 colour, running from the bafe towards the ex- 

 tremities. 



The fhiclds are of a dark fufcous colour, plain, 

 fmooth, and lie flat in the fubftance of the kaf, 

 fo as not to be higher than its furface. Tliey 

 have no rim or margin, but the fkin of the leaf 

 fupplies their place by covering a little of their 

 circumference, and this ikin is often crenated on 

 the edges.
