t OR this interesting addition to the British Algae we are
indebted to Miss Cutler, who finds it among other submarine
productions, and on rocks, at Sidmouth and Ilfracombe,
producing fructification in the autumnal months.
It is supposed to be perennial.
Fronds 3—6 inches in length, tufted, linear, attenuated,
compressed, sometimes irregularly divided, and bearing
numerous linear and attenuated pinnae; these are sometimes
distichous, sometimes secund, occasionally opposite. Fructification
consisting of small tubercles, clustered together
