Falkland*, etc.] FLORA ANTARCTICA. 319 A fully grown plant of this is very handsome ; I possess a specimen only a foot high, and with a simple stem, though branching so copiously above as to bear upwards of a hundred flowers, all fully blown and each nearly an inch and a half in diameter. 13.

Falkland Islands, abundant, especially amongst loose quartz rocks on the hills ; D? Urville, Capt. Sulivan, Mr. Chartres, J. B. H. A very handsome and singular plant, almost confined to the " Streams of stones," which are those curious tracts of land covered with loose blocks of quartz, abounding in some parts of the Falkland Islands. There the Nassauvia serpens grows, sending its brittle stems, several fathoms long, down amongst the masses of rock, till they reach the soil, often at a considerable depth. The plant varies somewhat in the foliage, the leaves being suberect or recurved, and more or less silky. Plate CXIV.
