Hab. Strait of Magalhaens ; Port Famine ; 17 Urville et Jacquinot. Hermite Island ; on trees in the forest and on rocks from the sea to an altitude of 1200 feet in large tufts.
Larger than the specimen figured in the 'Musci Exotici'; the capsules inclined, substrumose, the teeth of the peristome united regularly in pairs by transverse bars, pale yellow, leaves nerved half-way.
28. LESKIA, Hedwig.
1. Leskia nitida, Hook. fil. et Wils. ; caule vage ramoso, ramis longiusculis subsimplicibus teretibus, foliis imbricatis suberectis ovato-oblongis acuminatis concavis integerrimis basi binerviis, seta lsevi, theca cylindracea suberecta curnila, operculo brevirostri. (Tab. CLIV. fig. VI).
Hab. StatenLand; A. Menzies, Esq. (1787). Hermite Island ; Cape Horn ; barren.
Catdes sesquiunciales, steriles longiores, molles, virides ; rami teretes, filiforraes, apice e foliis convolutis cuspidati. Folia dense imbricata, erecto-patentia, ovato-oblonga, acuminata, acumine vix tertiam partem folii sequante, concava, subconvoluta, mtegerrima, nervis basilaribus duobus instructa, lutescenti-viridia, sericeo-nitentia, temussime elongato-areolata ; perichaetialia longiora, subsquarrosa. Seta unciahs, tortilis, gracilis, rubra. Theca cylindracea, suberecta, curvula, interdum suhcemua, basi attenuata, brunnea. Operculum basi conicum, rostello obliquo, capsula dimidio brevius, badium. Annulus operculo adherens. Peristoma externi dentes lutei, linea media notati, acu- minati; iuterni processus breviores, angusti, carinati, ciliolis nullis.
This moss has considerable resemblance to Hypnum stramineum, but differs in having the leaves almost piliferous, in the rostrate operculum and in the structure of the peristome. It is also allied to Hypnum crinitum, nobis, from Van Diemen's Land.

29. HYPNUM, Bill.
a. Foliis distichis.
1. Hypnum polifum, Hook, fil et Wils.; caule ramoso compresso, foliis disticliis patentibus oblongis compresso-carinatis subpiliferis integerrimis enerviis, seta lsevi, theca suberecta oblonga. (Tab. CLIV. fig. II.)
Hab. Hermite Island; common in woods near the sea. Kerguelen's Land; in rocky places (barren).
Caules unciales et ultra, csespitosi, subramosi, complanati, distiche ramosi ; rami compressi. Folia arete imbricata, patentia, disticha, elhptico-oblonga, scaphaefovinia vel compresso-carinata, apice cucullata, subpilifera, integerrima, enervia, tete viridia, sericeo-nitentia, tenuissime areolata ; pericheetiaha ovata, longe acuminata, erecta, integerrima, caulinis duplo breviora. Seta vix unciahs, lsev's, rufo-fusca. Theca oblonga, suberecta, sub-apophysata, ore patulo. Peristoma externi dentes lutei, incurvi, linea media notati ; interni cilia ciliolis interpositis. Calyptra dimichata, straminea. Operculum non visum.
A beautiful species, unlike any hitherto described.
