This is by far the most beautiful species of the genus, apparently common to the islands of the high South- 

 ern Indian and Pacific Oceans, but hitherto unknown among the Antarctic American groups. It was first 

 detected on M c 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 Ker- 

 guelen'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 sub- 

 jected to pressure.
