264 connected from the temperate regions of the North, in the case of Australia and New Zealand by water, and of the Cape by the deserts of Africa. This absence of Ruli is certainly an anomaly in the Chilian, Fuegian, and Patagonian Floras, which more fully represent in other genera common forms of European vegetation than do any other countries in the same latitudes.

This plant takes the place of R. saxatilis of the northern hemisphere and of R. Ounnianm of Tasmania. It is one of the few esculents of Fuegia and the Falkland Islands; the berries being almost as large as raspberries, of the colour of the Scottish cloudberry, R. chamcemorus, and with a very agreeable flavour.

I have seen only one specimen, which is stunted and has a very large rhizoma. The species inhabits the west coast of North America attaining the parallel of 48°. The leaflets are frequently remote, and in an individual from the Saskatchawau river there is only a solitary leaflet to one of the petioles.

Hab. Chonos Archipelago; C. Darwin, Esq.

A very widely diffused plant in the northern hemisphere, and perhaps not uncommon in the southern, being found both in Chiloe and Chili, though possibly introduced. It grows throughout Europe, from the shores of the Mediterranean to the Arctic Sea ; over all Asia to the north of the Altai range; in North America from latitude 40° to Whale-fish Island in 70° north latitude, and from the Oregon River to Kotzebue's Sound on the west coast. It is frequent in Tasmania, but is not indigenous there.
