Merrettia alpicola, Gray Arr. i., 349. 



"Mountain dulse," of the Scotch. 



On moist rocks. 



" 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 1-1^ inch, in diameter, flatfish, somewhat orbicular, 

 between coriaceous and gelatinous, when dry almost horny, of a deep but 

 dull purple colour, much lobed and curled like some Gyroplioroe, filled 

 with crowded clusters of granules, which, if minutely examined are found 

 to he mostly arranged in fours " Hooker. 



In Scotland it is called Mountain Dulse, and, according to Lightfoot. 

 " the Highlanders wash it and rub it between their hands into some 

 water, so as to make a thin pulpy mixture, with which they purge their 

 calves."
