This moss might readily be taken for a slender state of the H. elongatum, nobis, from which it is tndy distinct
in the lower part of the leaf being subquadrate, angled on each side a little above the base, thence tapering gradually
to a point, in the margin being more minutely senated, the nerve stronger, and in the smaller reticulation.

TMs is one of the discoveiies of my zealous friend Dr. Lyall, the value of whose collection is particularly noticed
in the preface to tMs work. The number of mosses aud sea-weeds especially, brought home from the Antarctic
regions, was much increased tM'ough that officer’s unwearied exertions.
Nearly allied to the H. crispifolium, Hook. (Muse. Exot. t. 31), but smaller, with the leaves neither plicate nor
falcate.

H a b . CampbeU’s Island; on the ground, barren.
Caules sesquiunciales, vage ramosi ; ramis 1 mic. longis, ad apices e foliis arcte convolutis cuspidatis. Folia
valde coucava, ad apices rotundata, obtusissima, basi latissima, truncata, subauriculata, pallide luteo-viridia, subscariosa,

AlUed to H. cochlearifolium, but with the habit of a Leskia, and readily distinguished by its cuspidate branches,
wider and more flaccid leaves wMch are singularly broad and ti-uncate at the base, where also there are a number
of lai-ge peUucid ceUs ; the seta also is longer aud more slender.
The above description has been drawn up in part from fertUe Tasmanian specimens, gathered in that, coimtry
bv J lr. Lawi-ence. There are in the Hookerian Herbarium several allied undescribed species, both from New Zealand
and Tasmania. A Euegian moss, Hypnum ? auriculatmn, Mont., (Voy. au Pole Sud, Bot. Crjqitog., t. 20. fig. 3),
is the American representative of tMs, it differs in haring the base of the leaves produced on each side into two
lobes.

H a b . Lord Auckland’s group and Campbell’s Island ; at the foot of precipices near the tops of the
mountains, altitude 1 2 0 0 -1 4 0 0 feet; barren.
Tills moss is a native of the woods of New Zealand, even as far north as lat. 36° S. ; hence its occun-ence only
at the tops of mountains iu the most bleak and exposed situations of so Mgh a latitude as Campbell’s Island was
quite unexpected. We cannot distinguish it fi-om more luxuriant northern specimens in its barren state.

* The Hypnum fiexile, Hedw., is a very difierent moss from tMs, as may be iufeired from the following description
