Strait of Magalhaens, Commerson; Fuegia, Banks and Solander, and found by all succeeding voyagers, throughout that country.

One of the most abundant of Puegian plants, exceedingly variable in the size of its foliage. Owing, apparently, to the puncture of an insect, the apices of the raniuli in the present and following species frequently assmne the form of cones, being covered with densely imbricated leaves so metamorphosed as exactly to resemble the scales of an Abies.

Though Protean in its fobage, this species is very confined in its geographical limits, advancing no further north than Cape Fairweather, on the east coast of Patagonia.

Hab. Var. &alpha;. Prom Cape Tres Monies (Patch Cove, alt. 2,000 feet), on the west coast of South Chili to Cape Horn, and in the Falkland Islands, Commerson, Banks and Solander, Forster, and all succeeding voyagers.

The two plants here united under one specific name are decidedly mere varieties. The &beta;. empetrifolia is by far the most abundant, and its prostrate stems sometimes attain the length of two feet. Var. minor, in its smallest
