Dulse (?), n. [Cf. Gael. duileasg; duille leaf + uisge water. Cf. Whisky.] Bot.
A seaweed of a reddish brown color, which is sometimes eaten, as in Scotland. The true dulse is Sarcophyllis edulis; the common is Rhodymenia. [Written also dillisk.]
The crimson leaf of the dulse is seen
To blush like a banner bathed in slaughter.
