This plant resembles, in some respects, the L . scariosa, Cass., but is very much larger, densely woollv in
many parts, with its leaves shorter and less regularly divided ; it also wants the pellucid glands which beset the
leaves of th a t species and contain a powerful essential oil.

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 KTQuarrie’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 veiy»^ 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.
