Islands, very abundant, Gaudichaud, and all succeeding voyagers.
The miserable natives of Fuegia weave the stems of this rush into baskets, and in doing so seem to exhaust
their cunning, for such baskets appeared to us to be the only article they possessed, exhibiting any attempt at
such haudy-craft as demands the sUghtest ingenuity, except, perhaps, the moveable heads of their sealing spears.
2. R ostkovia Magellanica, Hook. fil. I. e.

very abundant, Gaudichaud, ^'c.
I am not aware of this species having been gathered in Fuegia since Commerson’s time, except by myself; and
though abundant in Hermite Island, it is probably scarce and alpine to the north of that locality, as it is also in
Campbell’s Island.

Decidedly the most Antarctic Juncus, and exceedingly abundant at Cape Honi, the Falkland Islands, and
Kerguelen’s Land, where no other species of the genus exists. It is also a native of Campbell’s Island and
Lord Auckland’s gi’oup.

These, and other specimens gathered at ‘\'aldivia by Mr. Bridges, are the only extra-Australian individuals of
this species that I have seen. Meyer remaiks (Herb. Hook.), that there is no specific difference between the
specimens of the New and Old World.

H a b . Chonos Arcliipelago, C. B a n o in , Esq.
The present species, like the former, can scarcely be considered truly Antarctic, merely entering the northern
limits which I have assigned to the Fuegian Flora. I t ranges on the coast from Valparaiso to the latitude of Chonos
Ai-chipelago and is also foimd on the CordiUera of Pci-u.
Meyer (Hook. Herb.) remarks that this hardly belongs to the genus Cephaloxys, on account of the structure of
its capsule.

I have seen but au imperfeet spceimeu of the L. Fermia,m, Desv., to wUcl. the present is manifestly very
closely related. E. Meyer (Herb. Hook.) observes, that though so much ahke in the young state, when older they
are very distmct species. The present is the most Antarctic of the genus, except the following, and is the South
American representative of the L. crinita (Tab. X L \H I.) of Lord Auckland s group.

My specimens are only sufficient to prove this plant to be a Lmula ; they are scarcely two inches high, with a
slender'stem, and nodding'small panicle; the whole somewhat r e s e m b l in g the Z. a r eK u te of Arctic Europe, whose
Antarctic representative it probably is.

The arrangement of ah parts of the flower ai-e quaternary in the specimens of this curious plant that I have
examined; in which respect it differs from the majority of, and in the albunhnous seeds from ah the order, Alis-
macca, ; without, however, shewing any further affinity with the Naiadacea,, in which order Dr. Lindley has placed it.
The habit of Tetroncimn is precisely that of Narthecium, but in most other points its alliance to Triglochin
is evident, particularly in the spicate inflorescence, concave segments of the perianth, which are obhquely placed,
tho upper being larger and inserted above the rest; in the extrorse, neaidy sessile anthers; the sohtary, basal,
anatropal ovules ; aud the erect seed, which, being albuminous, indicates an affinity with Junceo!.
