In tbe London Jom-nal of Botany we referred this plant with a mai-k of doubt, (and erroneously as it subsequently
appeai-s) to the Cal. Gauikhandii of Agardh : a Falkland Island species, with wlbch it seemed to agree in
many pai-ticidai-s. Our kind friend. Dr. Montague, has, with his usual bberabty, suppbed us with a portion ot
the original specimen of C. Gaudkliaudii, which proves to be quite distinct. Its nearest northern albes are
0. Arbuscula and 0. Brodiæi, 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 thau C. Brodiæi, having more opaque
stems. The vai-, ft. may be only an advanced state, having been gathered in the same locabty «-ith var. a., but tliree
months later in tbe season. I t chiefly differs in its more tender and gelatinous substance, and in the branches being
less densely clothed with ramub, aud nearly naked at the base. Its outward appearance is very much that of
C. tetragonum, Ag.

This curious plant is equally widely diffused iu the soutbern as iu the northern and tropical zones ; and the
specimens from the different localities arc very similar. Wliat we believe to have been this species was collected
in Kerguelen’s Laud, but no specimens appear to have been preserved.
