Statura variabilis, 3-pollicaris ad pedalem. Folia ]i ad 4 unc. longa, 1-3 lin. lata, plantis humilioribus latiora, fasciculata, erecta, substricta. Scapi dense lanati. Capitula f ad 1 unc. diametro. I quite agree with the authors of the Botany of the 'Voyage au Pole Sud', in referring this handsome plant to Cidcitium, of which genus it is the most southern species.

Hab. Strait of Magalliaens, throughout Fuegia and the Falkland Islands ; abundant, on sandy beaches.

This species is most allied to one of the radiate group, the S. SmitMi, DC. It abounds whei'ever sandy beaches occur, from Cape Fairweather on the Patagonian coast, to the south part of Tierra del Fuego. In the Falkland Islands it forms a rank herbage about a yard high in such situations.

Rami teretes, lana appressa vestiti. Folia omnia integerrima, uncialia, nunquam exemplaribus meis fasciculata. Capitula i unc. longa et lata.

This species may be recognized by the quite entire somewhat rigid and suberect leaves, by the elongated pedicels of the capitula, which are rather rounded at the base, half an inch long and equally broad. The leaves in MM. Hombron and Jacquinot's figure of 8. Hookeri are somewhat fasciculate ; the same state was gathered at Cape Fairweather both by Capt. King and Mr. Darwin.
