318 FLORA ANTARCTICA. [Fuegia, the 



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.

A very handsome species, abundant in the woods of Fuegia. 



20. Senecio cuneatus, Hook. til. ; herbaceus, glaberrimus, caule ascendente sulcato inferne folioso,

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. Pedunculus caule continuus, elongatus, 

 nudus, 3-uncialis, erectus, apice 3-cephalus. Pedicelli basi folio unico aucti, inferiore unciah. Capitula \ unc.

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.

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.
