1. enneifolius, Campd., ''Monogr. des Rum.'' p. 95. Fl. Antarct. pt, 1. p. 67.

South Chili; Chonos Archipelago, C. Darwin, Esq.

Falkland Islands; Berkeley Sound, undoubtedly introduced.

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

3. Acetosella, Linn., ''Sp. Pl.'' p. 481. ''Engl. Bot.'' t. 1674. Gaudichaud and D'Urville, l. c.

Falkland Islands; abundant near the settlements and on the mountains; Gaudichaud, &c.

This, and the R. Acetosa, L., included in Gaudichaud's list, I consider undoubtedly as introduced plants, of which the seeds, being eaten by the birds, are by then agency transported to otherwise inaccessible cliffs.

1. CHENOPODIUM, L.

1. glaucum, Linn., ''Sp. Pl.'' p. 320. ''Engl. Bot.'' t. 1454.

Var. &beta;, divaricatum; prostratum, ramosum, ramis gracilibus divaricatis.

Var. &beta;, Chonos Archipelago ; C. Darwin, Esq.

Evidently the C. glaucum of Great Britain, though the stem is more diffusely branched than in most English 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. 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 majusculis erectis subtilissime reticulatis.

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

Caules e radice descendente fusiformi solitarii v. plurimi, prostrati, 3-5-unciales, canalculati v. angulati, crassi, diametro penn&aelig; anserin&aelig;. Folia longe petiolata, petiolo &frac12;-&frac34; unc. longo, lamina &aelig;quilonga carnosa, utrinque opaca, siccitate flavo-virescentia. Flores fructusque multoties 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 C. polyspermum, 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.
