“ 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-Q 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 Oyrophoroe, 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.”

“ Thallus a few lines in diameter, gelatinous, somewhat areolate, or as

a far deeper colour than those of Cf. magma.”—Harvey.
