I much regret not finding the seeds of this fine species amongst my dried specimens ; a few were contained
in the old capsules when first collected, of which I neglected to make any note a t the time : if my memory does
not deceive me, they wære small and covered with a pearly white, very lax and much elongated outer membrane,
not unlike th a t of Narthecium ossiß'agum. It is most remarkable for the apparently entire suppression of one
of the bracteolæ at the base of the flower, and also differs from the two other species in having a coriaceous,
not indurated capsule. I t is more nearly allied to the R. grandiflora {Marsippospeimiuni grandiflorum, Desv.)
than to R . Magellanica in size, in the creeping rhizoma, the solitary leaf sheathed at the base, the unequal outer
leaflets of the perianth, and in the long capsule and lax outer coat of the seed ; that plant is however of a much
larger size, has longer rhizomata and scapes, with two or three bracteolæ below the flow'crs, and an almost woody
capsule. The seeds of R . grandiflora, like those of Juncus castaneus and especially of J . ti-iglumis, are fusiform,
invested with a loose, pale yellow, lax, glistening membrane, thickened on one side, denoting the position
of the raphe, and produced at both ends ; it is formed of elongated cellular tissue. The albumen is covered by
a rather thick inner coat, composed of hexagonal cellular tissue, and is pendulous in the cavity of the outer membrane
by the vessels of the raphe, w'hich, arising from near the funiculus, terminate in a broad dark-coloured
chalaza at the top of the inner coat. The small quadrate embryo is placed at the lower or opposite extremity,
close to the apex, which is acute and discoloured.

This appears to be a veiy distinct species, most nearly allied to the L. Alopecurus, Desv., of Tierra del Fuego
and the Falkland Islands, a plant which ili-. Kimth considers as a foim of L. Pemviana, Desv., and which much
resembles the present in size, general appearance, and in aU particidars but the segments of the periaiitli, which aiæ
iu T. Alopecurus lacerated and fimbriated at the scarious margins, like the bracteolæ. I t also resembles some states
of L. campestris, I). C., as that plant appears in Tasmania, but the leaflets of the perianth are nearly scarious throughout
ill that species, more plane and not so thick and coriaceous ; the outer ones are also in this very coniæx and
distinctly carinated above the middle.

A close examination of this species with the Gaimard'ia australis (Gaudicliaiid iu Freyc. Voy. Bot. p. 418. t. 30),
has satisfied me that they are, as far as I can judge without flowers or fruit, congeneric. The habit of the tw'o
plants is entirely the same, and both form extended plane hard gi-een tufts on the bare hoggy smface of the hills in
their respective islands, often of two or three yards across. The present is rather the smaller species, with much
smaller leaves, not flattened on the upper surface, ciliated at the back about the middle, as also on the sides and
margins of the sheaths, which arc produced upwards into a shorter ligula than in G. australis.
