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. Ohileme, of Meyer, of which a
whoUy iusufficient character is given in a foot-note to that traveller’s journey (Reise un die Erde. vol. i. p. 364).
Its nearest ally is the T. iecipiens, Br., of Australia, of which T. filifolumi, Sieb. (inaccurately described as wanting
the abortive carpels), is a sj-nonym ; indeed, the Australian differs from the South .Ymerican plant only in the larger
fruit, so far as my only specimen enables me to judge.

A particulai-ly abimdant 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 m Tasmania.

It is diffioult to suppose that a plant, so abnndant 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 veiy likely may.

Evidently the Eui-opean E.palustris, wldch is also a native of Patagonia, and very widely diffused throughout
the temperate regions ot both the northern and southern hemispheres. Hypogynous setæ are generally present,
tliough those of my specimens vary in size ; Kunth says, “ setæ plane abortientes in Scirpo inelamstachjo,” and
D’Urville and Brongniart have, from their occasional absence, included this species in Firnbrisiylis.

The variations in the size, form, and markings on the surface of the achænia of the otherwise almost identical
forms of Isolepis seem really endless. FaUdand Island specimens are short, with smaU spikes, and small fuscous
achænia, wHch are broader than long and pnnctulate, but the puncta not in parallel lines. Mr. Darwin’s plant is
much longer, and has rather longer spikes, with eUiptical ovate lai-ger achænia, which are longer than broad and
similarly punctulate, its cuUus are often ten inches long. The J. lepida, Nees (in Linnæa, vol. iv. p. 291), judging
by Cuming’s Valparaiso specimens (in Herb. Hook.), resembles the plant of Mr. Darwin, its .achænia are precisely
similar to those of the Falkland Island var-iety in form, colom- and surface, but scarcely half as large.
The Cape of Good Hope I .pygmæa, so caUed by Kunth, has the achænium of I. lepida, but pale coloured and
smaller stiU ; wliUe the Auckland Island I. AuchlatAica (p. 88. t. L) has larger fruit than any.
All of the above differ from the Em-opean I. Savii, Seb. and Manr., in the achænia not being so deeply punctate
or striate. In size and form the pericarp of I. Savii resembles that of the Falkland Island plant.
