This is by far the most beautiful species of the genus, apparently common to the islands of the high Southern Indian and Pacific Oceans, but hitherto unknown among the Antarctic American groups. It was first detected on Quarrie's Island, whence specimens were received by Mr. Frazer in New Holland, and by him transmitted to England; but it is not ascertained who found them, though it is more than probable they were gathered by some person accompanying a sealer. It is the only Composite plant as yet known to inhabit Kerguelen's Island, where it covers very large tracts of ground with its silvery and beautifully feathery foliage, smelling strongly, but not unpleasantly, of parsley. The female corollas of both species are represented as they being of my original sketches: when dried they seem much more compressed, their membranous texture appear in such extreme tenuity, that it is probable they never recover their original form after once being subjected to pressure.
