Sea-shores, frequent.— /3. Appin, Capt. Carmichael. $ . Fructification
in Winter and Spring.— An elegant and delicate species, with leaves from
4 to 6 or 8 inches length, of a fine rose colour, having deeper coloured
veins. The fructification is generally found on the battered stalks and
midrib. The var. fi. is a singular and beautiful state of this plant, w ith
leaves 4 inches in diameter, and hardly more in length, obtusely lobed
and plaited. (Carm.)
2. D. sinuosa, Lamour. (sinuous-leaved Delesseria); stem
cylindrical branched, frond at length pinnated with oblong den-
tato-sinuate or pinnatitid transversely veined erenated leave-
ciliated at the margins with seed-hearing Leaflets, spluerical cap-
