290 NOTES ON THE BOTANY 
Island Usnea, being larger and more handsome; also 
some beautiful species of Sticta and Roccella, and several 
Cladonie. 
* My Sea-weeds are not examined, and I shall send none 
of them home till I have done so. There are three species of 
Macrocystis, and several Laminaria, here taking the place of 
the Sargassa of milder climates, some lovely Floridee and the 
Ballia, one of the commonest sea-weeds here, and attaining a 
large size. I do not doubt its being the Sphacelaria callitri- 
cha of Agardh. 
* Marine Confervoid species are abundant, many of the bays 
being covered with an odious-looking green slime, formed by 
one or two kinds. There are also several fresh-water species. 
* Fungi are scarce. On our first arrival, two large Agarics 
and a yellow Helvella (?)) were common, but I neglected to 
gather them, and when the cold weather set in, they imme- 
diately vanished. I have, however, requested my friend, M. 
Lyall, of the ‘ Terror, to collect them when the spring be- 
gins, at which time we shall be absent at Cape Horn, and I 
have provided him with a bottle of spirits for the purpose. 
The other Fungi are two small Aygarics, a Lycoperdon and a 
Peziza. 
* Of Ferns I possess two Lycopodia, two Steganie, the Hy- 
menophyllum cespitosum (the smallest fern I ever saw), & 
handsome new Aspidium, very rare, and gathered last week 
in the stream of stones described by Darwin, and a Gleichenia, 
kindly given me by the Assist.-Surgeon of H.M.S. * Arrow,’ 
but which I have never seen alive. 
* Since beginning this letter, I have taken a long walk to 
visit Uranie Bay, where the French navigator, Freycinet, lost 
his ship, * L’Uranie? Leaving our anchorage, I proceeded 
to the south end of the upper extremity of this harbour, along 
a slaty beach, overhung with low cliffs of clay-slate, covered 
with Gunnera, Acena, Ozalis enneaphylla, Cardamine. glacia- 
lis, Nassauvia Gaudichaudii, Homoianthus echinulatus, with 
here and there bushes of Empetrum rubrum and Chiliotri- 
chum amelloides, and many smaller plants, some of them mari-
