Var. /3, foliis anguste linearibus acurninatis integerrirnis, involucri squamis glabriusculis angnstioribus. 



Hab. a and /9, Strait of Magalliaens, Port Famine ; Capt. King. 



Folia li- 2 unc. longa, integerrima v. versus apices dilatata et 2— 4-lobata, acuta v. acuminata, lana decidua. 

 Pedicelli 2-3 unc. longi. Capitula |- unc. longa. 



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.

Hab. Strait of Magalliaens, var. a, Port Peckett ; MM. Hombron and Jacquinot. Var. /3, Port 

 Peckett; H. and J. Port Gregory; Capt. King. 



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. 



5. Senecio Jtoccidus, Homb. et Jacq. in Toy. auPote Surf, Bot.Dicot. Phan. 1. 12. e.

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

7. Senecio Zaseguei, Homb. et Jacq. 1. c. t. 13. D. 



Hab. Strait of Magalliaens, Port Peckett; MM. Hombron and Jacquinot. 



I am quite ignorant of these two species, which seem to belong to this section, but of which no descriptions 

 have hitherto appeared.
