244 FLOKA ANTARCTICA. [Fuegia, the 



pliylla*, mihi, (vid. infra) the stamens are definite and invariably four or five in number, alternating with as 

 many conspicuous obcordate fleshy flattened glands, placed rather externally to them and alternating also with the 

 segments of the calyx, to which the stamens are opposite. The filaments are flattened, and the anthers decidedly 

 extrorse, an arrangement probably common to the other species, where, owing to the filiform and slender filaments, 

 it escapes notice. The ovary has three lines of parietal placenta? : there are four in some other species, A . lanceolata, 

 A. Chiloense, and A. serrata, whose ovaries I have examined.

A native both of the east and west sides of South America, in the former inhabiting the coast at Cape Farewell 

 and the Falkland Islands, and on the west side re-appearing at Chiloe and Valdivia, and passing thence north to 

 Conception ; a singular distribution, for I have seen no specimens from the Strait itself, which is Commerson's 

 habitat, according to De Candolle. The two varieties, constituted by Poiret, are hardly of sufficient importance to 

 be retained, though De Candolle has done so, under the names of a, megapliylla and /3, micropliylla.
