In the London Journal of Botany we referred this plant with a mark of doubt, (and erroneously as it subsequently appears) to the Cat. Gaudicliaudii of Agardh: a Falkland Island species, with which it seemed to agree in many particulars. Our kiud friend, Dr. Montague, has, with his usual liberality, supplied us with a portion of the original specimen of C. Gaudicliaudii, which proves to be quite distinct. Its nearest northern allies are C. Jrbuscula and C. Brodim, between which it appears almost intermediate, having the large size and robust habit of the former, with longer and more compound pinnules, and being much stouter than C. Brodiai, having more opaque stems. The var. 0. may be only an advanced state, having been gathered in the same locality with var. a., but three months later in the season. It chiefly differs in its more tender and gelatinous substance, and in the branches being less densely clothed with ramub, and nearly naked at the base. Its outward appearance is very much that of C. tetragonum, Ag.

This curious plant is equally widely diffused in the southern as in the northern and tropical zones ; and the specimens from the different localities are very similar. What we believe to have been this species was collected in Kerguelen's Land, but no specimens appear to have been preserved.
