I bave presumed this to be the A . Magellanica of Lamarck, for it agTees with his insuificient description,
and also with the longer one given by Poiret, except that the awn is not terminal, though so described (possibly
tlirough inadvertence) by that author. As a species it is very neai-ly allied to the folloiring, but may be distinguished
by the larger glumes, gi-eater size, and conspicuous upper palea.

Agrostis Antaretica is one of the most abundant of grasses in the regions it inhabits, especially in swampy
grounds, which seem pai-ticularly favourable to its growth. I t is also a very elegant plant, from its gi-aceful
habit and the form of its nodding panicle. It may be the true A . Magellanica of Lamarck, and judging from its
abundance, appears natural to suppose so ; but the very short upper palea is not alluded to in that author’s
description, and Poiret’s observation that the upper is the longest, would imply that there is no remarkable
difference in their length. Considering the invalid natm-e of the characters afforded by the comparative length of
the palea in this genus, it is probable that this and the preceding are but varieties of one and the same plant.
Kerguelen’s Land specimens are frequently monstrous; the lower glame being then provided with two
parallel distmct nerves, and in other cases I have seen thi-ee distant valves, two outer and one inuer. The lower
palea again has the arista sometimes placed ou one side of its base.

The four-aristate lower palea of this species distinguishes it at once from any of its congeners. Mr. Darwin’s,
and one gathered in Chiloe by Capt. King, are the only specimens I have seen.

A fine species and first pointed out to me by my friend Governor Moodie, as forming, next to the Tussock,
the most useful grass in the Falkland Islands, for fodder. I t abounds both in wet and dry places, in the upland
and low gi-ounds, affording exceUent pasturage, and even when cut and dried it is eaten with avidity by horses,
sheep, and cattle. Avery similar congener inhabits th e ' lofty peak of Tolima, in New Grenada, north of the
Equator.

H a b . Strait of Magalhaens and throughout Fuegia and the Falkland Islands, very abundant, Banks
and Solander, and aU succeeding voyagers.
Under H. redolens, in the fii-st part of this work, I have pointed out the very slight distinctions that separate
this plant both from it and from the Tasmanian E . Antarctica, B r .; I consider them scarcely vaUd, though constant
in specimens from the three ividely separated localities they inhabit. In the Falkland Islands this grass is
particularly abimdant, forming large tufts and often beds, especiaUy near running water and on wet rooks close to the
sea, and is much frequented by sea-birds, as a building place. The scent is very strong, and retained in the dried
specimens. Living plants introduced, by means of Ward’s cases, into the Kew Gardens, have flourished luxuriantly,
liitherto without flowering.

An exceedingly abundant Fidkland Island grass, and a great ornament to the black peat bogs, which are
frequently clothed witli its elegant purple panicles. The foliage is too sc.anty and of too rigid a texture to aftbrd
good pasturage.
I do not detect any diflerence between Falkland Island and European specimens. Mr. Watson remarks that
this is, perhaps, the A. uliginosa, Weihe; a plant I do not know, but quoted by Kunth as synonymous with
A.jlexuosa.
