Brytm nutans, Schreb. ; caule subramoso breviusculo v. elongato, fobis superioribus elongato-lanccolatis apice serratis inferioribus ovato-lanceolatis integerriniis, theca nutante v. pendula oblongo-pj-riformi longitudine varia, operculo majusculo convexo papillate B. nutans, Schreber, Fl.

Hab. Lord Auckland's group; on the hills, at an altitude of 1000 feet; rare, growing in a peaty soil.

The description given above is mainly taken from the 'Bryologia Europsea,' the authors of which add to the specific character " hermaphroiUtum, antheridiis per paria in foliorum summorum perichartialiunique axillis inque archegonioriun receptacido." The Auckland Island specimens are immature and vary in size, but coincide well with others of British growth. This is a moss of a high arctic as well as antarctic latitude.

2. Beytjm Wahlenbergii, Schwaeg. ; caule simplici erecto v. ascendente, foliis apices versus serratis inferioribus remotis ovatis acuininatis, caulinis confertis lanceolatis costa evanida instructis, theea inclinata v. pendula brevi pjrifonni, operculo convexo v. subconico mamillato, dentibus majusculis. B. Wahlenbergii, Schwaeg. Suppl. vol. i. pt. 2. p. 92. t. 70. Bruch et Schbnper, Bryol. Europ. Fasc. G-9, p. 44. t. 19.

Hab. Lord Auckland's group ; barren. (Br. By all.)

The inflorescence of this moss is dioecious.

3. Brytjm llaadnm, Hook. fil. et TTils. ; caule subsimplici, foliis imbricatis erecto-patentibus oblongis obtusis integerrimis concavis, nervo tenui subcontinuo, theca — ? (Tab. LX. Fig. I.)

Hab. Campbell's Island ; in boggy places, frecoient, but barren. Caules pollicares, csespitosi, parce ramosi, flaccidi. Folia subereeta, laxe imbricata, valde concava, membranacea, pellucida, laxe reticulata, areolis rhomboideo-hexagonis, marginibus non reflexis, siccitate appressa, contracta, nitida, iufima rubella v. rosea, superiora pallide viridia, nervo rubello sub apicem v. evanido. Fructus deest.

A very beautiful moss, remarkable for its brilliant reddish and very membranous foliage. Allied to B. celhdare, Hook, (in Schwaeg. Suppl., t. 211 a, idem ac Poldia tiirhhiata, Schwaeg., I.e. t. 194?); but the leaves are larger, much more concave and obtuse, and the stems longer.

4. Bbtum truncorum, Brid. ; caule erecto subsimplici, fobis marginatis obovatis serratis longe acuininatis supremis rosulatis, theca pendula elongata cyHndracea, operculo brevi conico apice acuto. B. truncorum, Brid. Bryol. Univ. vol. i. p. 699.

Hab. Campbell's Island ; 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 with Bridel's description of B. truncorum, a Bourbon plant, detected by Bory de St. Vincent. Our moss is closely allied to the B. ramosum, Hook. (Ic. Plant, t. 20. f. 2), and also to B. patens, Hook, and TA lis. (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 narrow elongated theca. It is perhaps the B. leptothecium, Tayl. MSS.

5. Bryoi (innulatuiii, Hook. fil. et Tils.; caule perbrevi, fobis patentibus subrigidis ovato-lanceolatis acutis integerrimis sobdinerviis, theca pendida ovata, operculo conico, annulo latissimo. (Tab. LX. Fig. II.)

Hab. Campbell's Island ; on the low grounds, scarce.
