‘* 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 w considerable extent. 
Each frond is 1-14 inch. in diameter, flattish, somewhat orbicular, 
between coriaceous and gelatinous, when dry almost horny, of a deep but 
dull purple colour, much lobed and curled like some Gyrephore, filled 
with crowded clusters of granules, which, if minutely examined are found 
to be 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.”
