wide range in the temperate, but not in the tropical regions ; for, though found in the Azores, Madeira, and the Canaries, it is absent in Ascension, and St. Helena; re-appearing in the Falklands ; and while in the Pacific it inhabits New Zealand, and Juan Fernandez, it is not seen on the tropical South Sea Islands or the Galapagos. It abounds along the coasts of Europe, and shores of the Mediterranean, attaining the latitude of Shetland in the British dominions, and even entering the Arctic circle in Lapland. In Africa it grows at the Cape of Good Hope; but not on any part of the coast between that point and the mouths of the Nile. Further east, in Australia, this little plant commences in the parallel of 30°, thence extending to the extreme south of Tasmania. Arctic America presents it both on the east and west coasts, viz., California on the Pacific side, and Texas on the Atlantic. In South America, again, its range commences at Valparaiso, and terminates at Cape Tres Montes on the west, and it also inhabits the country lying between South Brazil and the Falklands on the east.

An abundant and exceedingly variable Falkland Island plant, especially in the comparative length of its capside, which is sometimes only half the length of, and at others, longer than the calyx. It is also very common in Chili, Patagonia, and in South Brazil.

Of this species there are but imperfect specimens in the herbarium of Mr. Darwin, by whom only it has been gathered ; though without root-leaves and fruit, it may be recognized by the long peduncles, large flowers, and especially by the size of the petals.
The peduncle of one specimen is single-flowered.
