Falklands, etc.] state, appears, at first sight, sufficiently distinct ; but it often runs out to a considerable length, when the leaves become much more laxly imbricated.

Both pink and white berries are found on this species ; also cones, similar to those described under P. mucronata, and diseased ramuli, densely covered with minute, erect, linear leaves.

Dr. Gillies' Arbutus vaccinioides, from the Andes of Chili, which appears identical with Poeppig's A. leucocarpa {Pernettya, DC), is most likely another form of this plant, the length of the pedicels affording no character either in the flower or fruit.

When figuring tins species, I gave it the trivial appellation of Antarctica, not being aware of its identity with Pernettya serpyllifolia, DC, and Arbutus serpyllifolia, Lam., all which names must yield to that of G. microphylla, the plant being undoubtedly the little-known Arbutus microphylla of Forster.

The genera Gaultheria and Pernettya are the representatives, in the high southern latitudes, of the Arbuti, of the family of Fricece in the northern and Arctic regions.

It is certainly very remarkable that the sole American representative hitherto noticed of the order Epacridea>, is also among the very few that so deviate from one of the most important diagnostic characters of that order, as to present a distinctly two-celled anther. Labillardiere rightly described the stamens of the Tasmanian Prionotes
