H ab. Lord Auckland’s g roup; on th e liiRs, at an altitude of 1000 feet; rare, grovring in a peaty soil.
The description given above is mainly taken from the ‘ Brj'ologia Europæa,’ the authors of which add to the
specific character “ hermaphroditiun, antherichis per paria in foborum summonun pcrichætiabumque arilbs inque
archegomonun receptáculo.” The Auckland Island specimens ai*e immature aud vary in size, but coincide well
with others of British grondh. This is a moss of a high arctic as web as antarctic latitude.
2. Bryxjm Wahlenbergii, Schwaeg. ; caule simpbci erecto v. ascendente, foliis apices versus serratis inferioribus
remotis ovatis acuminatis, caulinis confertis lanceolatis costa evanida instructis, tlieca incbnata v.

H ab. Lord Auckland’s group ; barren. {Br. Lyall.)
Tlie inflorescence of this moss is dioecious.

H ab. Campbeb’s Islan d ; in boggy places, fr’equent, b u t barren.
Caules poLbcares, cæspitosi, parce ramosi, flaccidi. Folia suberecta, laxe imbricata, valde concava, membranacea,
peUucida, laxe.reticulata, areobs rhomboideo-hexagonis, margimbus non reflexis, siccitate appressa, contracta, nitida,
infima rubeba v. rosea, superiora pabide viridia, nervo rubebo sub apicem v. evanido. Fructus deest.
A verv beautiful moss, remarkable for its brilbant reddish and very membranous fobage. Albed to B. cellulare.
Hook, (in Schwaeg. Suppl., t. 314«, idem ac Fohlia turbinata, Schwaeg., 1. c. 1 .194?); but the leaves are larger,
much more concave and obtuse, and the stems longer.

4. B ry u ii truncoruni, B rid .; caule erecto subsimpbci, fobis marginatis obovatis seiTatis longe acuminatis

Brid. Bryol. Univ. vol. i. p. 699.
H a b . Campbeb’s Is lan d ; in moist exposed places, barren.
These specimens seem to be of the same species as others gathered in New Zealand with capsules, and which
agree well udth Bridel’s description of B. trmcorum, a Bourbon plant, detected by Boiy de St. Vincent. Our moss
is closely albed to the B. ramosum. Hook. (Ic. Plant, t. 20. f. 2), and also to B. patens. Hook, and Wils. (Lond.
Journ. of Bot., vol. iii. p. 155), from which latter, as also from B. roseum, it differs in the margined leaves and in
the remarkably naiTow elongated theca. I t is perhaps the B. leptotkecium, Tayl. MSS.
5. B rtüm annulatum, Hook. fil. et Wils.; caule perbrevi, fobis patentibus subrigidis ovato-lanceolatis
acutis integerrimis sobdinerviis, theca pendula ovata, operculo conico, annulo latissimo. (Tab. LX. Eig. II.)
H ab. Campbeb’s Is lan d ; on the low grounds, scarce.
Caules cæspitosi, 2 bn. longi. Folia conferta, subconcava, nen'o erasso continuo vis excurrente instructa, siccitate
non crispata. Seta 3-4 bn. louga, apice arcuata. Theca subobovata. Feristomii externi dentes lutei, tra-
beculati, trabccubs remotis. Ammlus magnus, insignis, longitudine ^ peristomb exterioris.
We advance this species with much hesitation and after a veiy careful examination. I t is most nearly aUied
to the B. halanoides (Tayl. MSS.), of which it may possibly be a variety, differing from that moss in the rigid and
difierently shaped leaves, in the large annibus and distant trabeculæ of the outer teeth. The capsule is uot sufficiently
mature to show the nature of the cibæ of the iimer peristome.

1. E unaria hygrometrica, Hedw.; caule brerissimo subsimplici, fobis appressis ovato-lanceolatis integerrimis
nervo excurrente, seta arcuata madore torta, theca cernua pyriformi profunde sulcata, operculo

H^yb. Campbeb’s Island ; frequent on the hills ; not seen in Lord Auckland’s group.
The absence of this moss, in the parts of Lord Auckland’s group explored by the expedition, is very remarkable,
considering its abundance in Campbeb’s Island, and is doubtless owing to the presence of carbonized matter
over the sm-face of a gi-eat part of the latter island. In the Antarctic regions, as in Europe, the Funarioe invariably
fobow fh-es, and the confervoid filaments of its yomigest state constitute the first appearance of vegetation on the
burnt sob of the Falkland Islands.

H jYB. Lord Auckland’s group and Campbeb’s Islan d ; on moist rocks, at au elevation of 1400 feet in
the fonner and 600 in the la tter island.
The original specimen, figm*ed in the ‘ JIusci Exotici,’ has the leaves terminated by a slender hah-bke production
of their own length, whbst others, gathered by Hr. Lyab at Rio, ai-c muticous in that respect; those now
before us are intermediate, and some others from Cape Horn more closely resemble the moss of the iVndes.
