Distinguished from the foregoing, of which it may eventually prove a variety, by the larger and more flaccid foliage, by the very long and slender pedicels, the somewhat larger capitida, and narrower iuvolucral scales.

Caules exemplaribus meis varietatis /3 spithamaei, foliosi. Folia -i-f unc. longa, superiora integerrirna, pleraque apicem versus 1-3-dentata v. lobata. Pedicelli unciales, graciles. Capitula unc. longa, medio ex involucri foliolis paulo inflexis constricta.

The figure of the var. /3, given in the work quoted above, is very characteristic of Capt. King's specimens, but it may belong to a different species from the S. Danyausii, in which the capitula are represented larger and not constricted at the mouth of the involucre. A very extensive suite of the Magellanic Seneciones is required to settle the limits of the species, if they really are limited, for every different locality seems to furnish a form not found in another.

I do not recognize this species amongst those from South Chili, Fuegia and Patagonia that I have examined.

I am quite ignorant of these two species, which seem to belong to this section, but of which no descriptions have hitherto appeared. § II. Discoidese, glabrata v. glaberrima.
