According to Lightfoot, this is the " Mountain Dulse " of 

 the Scotch. 



" On the mountains of Arran this lies unattached among 

 loose wet stones, covering them in a straggling manner to a 

 considerable extent. Each frond is an inch or an inch and a 

 half in diameter, flattish, somewhat orbicular, between co- 

 riaceous and gelatinous ; when dry almost horny, of a deep 

 but dull purple colour, much lobed and curled, like some Gy- 

 rophorcB, filled with crowded clusters of granules, which, if 

 minutely examined, are found to be arranged mostly in fours."
