Hab. Falkland Islands ; Berkeley Sound, undoubtedly introduced. 

 My specimens, though imperfect, are, I think, referable to this species. 



3. Rtjmex Acetosella, Linn., 8p. PI. p. 481. Engl. Bot. t. 1674. Gaudichaud and D'Urville, I. c. 



Hab. Falkland Islands ; abundant near the settlements and on the mountains ; Gaudichaud, Sfc. 



This, and the R. Acetosa, L., included in Gaudichaud' s list, I consider undoubtedly as introduced plants, 

 of winch the seeds, being eaten by the birds, are by then agency transported to otherwise inaccessible cliffs.

 1. CHENOPODIUM, L. 



1. Chenopodium glaucum, Linn., Sp. PI. p. 320. Engl. Bot. t. 1454. 



Var. /3, divaricatum ; prostratum, ramosum, ramis gracilibus divaricatis. 



Hab. Var. /3, Chonos Archipelago ; C. Darwin, Esq. 



Evidently the ft glaucum of Great Britain, though the stem is more diffusely branched than in most Enghsh 

 individuals. A precisely similar variety inhabits British North America, but I have seen no specimens from any part 

 of the New World between that country and South Chili. 



2. Chenopodium macrospermum, Hook, fil.; glaberrimum, non glaucescens, caulibus validis succulentis 

 basi divaricatim ramosis, foliis petiolatis deltoideo-oblongis obtusis sinuatis carnosis, racemis compositis 

 densifloris aphyllis bracteatis, seminibus majuscuhs erectis subtilissime reticulatis. 



Hab. Falkland Islands ; Berkeley Sound and St. Salvador Bay, near the sea ; C. Darwin, Esq., J. B. H. 



Caules e radice descendente fusiformi solitarii v. plurimi, prostrati, 3-5-unciales, canahcidati v. angulati, crassi, 

 diametro penna? anserinse. Folia longe petiolata, petiolo 1-f unc. longo, lamina fequilonga carnosa, utrinque opaca, 

 siccitate flavo-virescentia. Flores fruciusque mtdtoties majores quam in affinibus. 



This very distinct species has been used as a pot-herb by the colonists of the Falkland Islands, and was 

 described to me as excellent. The great size of the seed at once distinguishes it from its nearest European allies, 

 C. rubrum, L., and ft polyspermism,, L. I have not included these two species under the genus Blitum because the 

 seeds of C. glaucum are more frequently horizontal than erect, and neither of them possesses a calyx which is 

 materially thickened after flowering.
