R-ather a scai’ce plant aud perfectly distmct from the foUowing, with which it has been strangely confounded,
partly because Gaertner inadvertently applied the name of A . trioispidata to his figure of Banks’ A . trifureata, and
partly ovdug to the confusion in wliich the whole group to which it belongs has long been involved, and the reference
of many different umbelliferous plants ivith a tufted habit aud simple umbels, by Lamarck, to the Bolax glebaria
of Commerson.

Foimd at all elevations, both in Fuegia and in the Falkland Islands, and so much resembling Colobanthus
suhîdatus, that the two plants have often been taken for each other and for the Mniarum fasciculatum, Forst., a New
Holland and New Zealand plant, which is hence erroneously described as being also a native of the Strait of
Magalhaens. The fruit of this species certainly differs from that of tbe two former, and they, again, from the carpels
of A. cæspitosa and the following ; I have, however, brought them all under one genus, feehng assured that the
details of the form of the mericarps do not afford the important characters in this group that they do in some
other UnibellifercB.

The fruit of this plant is so dorsaUy compressed and contracted at the sutures, as almost to justify its being
removed from this genus and even gi-oup. The calycine teeth and the styles are rather longer than is usual in
Azorella ; still, as mentioned above, the fruits of almost all the species that I have examined differ so ividely from
one another, that to separate this or either of the fonner would involve the complete dismemberment of a genus, of
which all the species, except the fohowing, are very closely alhed.
Azorella Selago is the most abundant plant in Kerguelen’s Land, covering the rocky ground close to tlie sea
with broivn masses many feet in extent, and often so soft that the traveher plunges into or through them up to the
middle. Like the curious Bolax glebaria of the Falkland Islands, the hving part of the plant forms a crust over a

specimens sent from M’ QuaiTie’s Island by Mr. Irazer.

Tliis plant differs so materially in habit from those described above, that I have placed it in a separate section
of the genus. The general aspect is altogether that of a Hydrocotyle, with the ftmit of an Azorella, to which genus
it was rightly referred by D ’Urville ; it also veiy much resembles the Fozoa reniformis, in P a il 1. p. 15. t. xi. where
the carpels are however very different. The fruit represented in Plate XCVIII is immatui-e ; when fully ripe, the
mericarps are more contracted at the sutm’e.

I have cndcai'oured to um-avcl the synonymy of this highly curious and now well-known plant, but cannot
ascertain what are the various species figiucd hy Lamarck and pai'tially described hy Ponet, hoth these ivriters
seeming to have had several in view.
