318 Hab. Tierra del Fuego ; abundant in marshy places on the mountains from Port Famine to Cape Horn, Banks and Solander, and all succeeding voyagers.

The very pale colour of the ray of this plant seems to have deceived the older authors in regard to its genus. In this respect it differs from the majority of Seneciones, as also in the apices of the involucral scales not being sphacelated. It is allied to the discoid S. Kingii, mihi.

Hab. Strait of Magalhaens ; Port Famine, Capt. King.

Caulis crassitie penna; anatmae, herbaceus. Rami axillares, abbreviati, superiores elongati, floiiferi. Folia patula, plana, subcoriacea, siccitate nigrescentia, 1-1- unc. longa, lata.

Apparently a most distinct species, of which I have but a very nnperfect specimen, collected by Capt. King; it resembles the S. nigrescens H. and A., of South Chili, but the foliage is different. 21.

Hab. Falkland Islands, very abundant; Gaudichaud, and all subsequent collectors.

As is stated under the S. FalMandicus, the varieties a and /3 of S. littoralis belong to two very different species. The one for which I have retained the name, is generally a maritime plant, usually growing in marshy places and never altogether woolly, or more so in its youngest state than when older. The leaves are extremely variable, straight or falcate, obtuse or generally acute, one line to nearly one third of an inch broad, strictly linear or obovato-lanceolate, sometimes, though rarely, obscurely siuuato-dentate.
