Hab. Cape Tres Montes, C. Darwin, Esq.
Variat magnitudine, scapoque foliis nunc longiore nunc multoties breviore.
Probably a very widely diffused, and certainly in size a variable plant, common to both coasts of extra-tropical South America, and to the Cape of Good Hope. To this may also belong the T. Chilense, of Meyer, of which a wholly insufficient character is given in a foot-note to that traveller's journey (Reise un die Erde. vol. i. p. 354). Its nearest ally is the T. decipiens, Br., of Australia, of which T. filifolium, Sieb. (inaccurately described as wanting the abortive carpels), is a synonym; indeed, the Australian differs from the South American plant only in the larger fruit, so far as my only specimen enables me to judge.

Hab. Fuegia; Hermite Island, Gape Horn, J. D. H.; Falkland Islands, very abundant, Gaudichaud, D'Urville, J. D. H.
A particularly abundant plant on the hills of the Falkland Islands, forming, in boggy places, hard, extensive green patches, often several yards across, and contributing materially to the formation of peat-bog. It has representatives on Lord Auckland's Group and probably likewise in Tasmania.

Hab. Fuegia; Hermite Island, Cape Horn, J. D. H.; Falkland Islands, abundant, Gaudichaud, D'Urville, J. D. H.
It is difficult to suppose that a plant, so abundant in the Falkland Islands, should be rare on the mountains of the adjacent continent, where, however, it has only been gathered near Cape Horn, unless a species collected by M. Goudot full 4,000 miles further north, on the peak of Tolima in Colombia, should prove to be the same plant, as, judging from a barren specimen, it very likely may.
