Caulk procumbens, uncialis. Rami conferti, fastigiati, ubsimplices, graeiles, fragiles. Folia subsecunda, siccitate erecta, subappressa, vix pilifera, concava, luride viridia, areolis hnearibus.
Allied to H. extenuatum, Brid., but smaller, the leaves more erect, and tapering gradually to a very narrow point.

9. Hypnum chlamydophylhm, Hook. fil. et Wils. ; caule prostrate subranioso, ramis simplicibus elongatis cuspidatis, foliis imbricatis patentibus quadrato-rotundatis integerrimis basi trimcatis concavis nervo breviusculo evanido, seta elongata gracili leevi, theca cernua ovato-oblonga,, operculo conico. (Tab. LXI. Fig. I.)
Hab. Campbell's Island ; on tlie ground, barren.
Caules sesquiunciales, vage ramosi ; ramis 1 unc. longis, ad apices e foliis arete convolutis cuspidatis. Folia valde concava, ad apices rotundata, obtusissima, basi latissima, truncata, subauriculata, pallide luteo-viridia, subscariosa, pellucida, splendentia, nervo simplici infra mediimi evanido v. nervis duobus brevibus, areolis anguste oblongis inferioribus midto majoribus ; peric/iatialia erecta. Seta fere 1-J- unc. longa, gracilis, laevis, torta, rubra. Theca cernua v. horizontalis, ovato-oblonga, brunnea. Peristominm luteum. Operculum breve, theca concolor.
Allied to H. coclilearifolium, but with the habit of a Leskia, and readily distinguished by its cuspidate branches, wider and more flaccid leaves which are singularly broad and truncate at the base, where also there are a number of large pellucid cells; the seta also is longer and more slender.
The above description has been drawn up in part from fertile Tasmanian specimens, gathered in that country by Mr. Lawrence. There are in the Hookerian Herbarium several allied uudescribed species, both from New Zealand and Tasmania. A Fuegian moss, Hypnum ? aurkulatum, Mont., (Voy. au Pole Sud, Bot. Cryptog., t. 20. fig. 3), is the American representative of this, it differs in having the base of the leaves produced on each side into two lobes.

10. Hypnum cocJdearifoUum, Sclrwaeg. ; caule subrepente, ramis ascendentibus apice radicantibus, foliis imbricatis subrotundis obtusiusculis concavissimis subhemispliericis enerviis, theca cernua ovata, operculo conico. H. flexile[1], Hook. Muse. Exot. 1. 110. [excl. syn. Swartzii, Hedwigii, et Schwaegr.)
Hab. Lord Auckland's group and Campbell's Island ; at the foot of precipices near the tops of the mountains, altitude 1200-1-100 feet; barren.
This moss is a native of the woods of New Zealand, even as far north as lat. 30° S. ; hence its occurrence only at the tops of mountains in the most bleak and exposed situations of so high a latitude as Campbell's Island was quite unexpected. We cannot distinguish it from more luxuriant northern specimens in its barren state.
11. Hypnum Arluscula, Sw:; caule erecto bipinnatim ramoso, foliis imbricatis erecto-patentibus ovatis
- ↑ The Hypnum Jlexile, Hedw., is a very different moss from this, as may be inferred from the following description drawn up from an authentic specimen : —
hzsKiAjlexilis, Hedw. ; eaule pendulo subpinnatim ramoso, foHis ovato-oblongis rigidiusculis apicnlatis (apiculo recurvo) enerviis, perichsetialibus squarrosis, theca erecta elliptica, operculo subulato, calyptra valde pilosa. — L. flexilis, Hedw, Sp. Muse. p. 234. t. 58. Hypnum? Swwrtz, Prodr. p. 141. Fl. Incl. Oee. p. 1830.
Hab. Jamaica ; on the tops of mountains in the southern parts of the island, (S/cart:).
