Has. Hermite Island; on moist banks, wet rocks, &c., not uncommon, (barren). 
3. Hypnum reticulatum, Hook. fil. et Wils.; caule erecto simpliciusculo, foliis distichis patentibus 
ovato-lanceolatis acuminatis vix piliferis submarginatis reticulatis apice serrulatis, nervo tenui subexcurrente. 
(Tas. CLIV. Fig. V.) 
Haz. Hermite Island; on the ground in damp woods, rare (barren). 
Caules laxe ceespitosi, unciales, subelongati, erecti, plerumque simplices, complanati, molles. Folia disticha, 
patentia, subobliqua, acutissima, fere pilifera, areolis marginalibus angustioribus confertis, ceeteris majusculis sub- 
rhomboideis, recentiora leete viridia, nitentia. 
The many points of correspondence between this moss and Bryum vagans, nobis, have not escaped our notice. 
The specimens being few and barren, we are unable to pronounce with confidence on the validity of the species. 
` Tt differs from H. subbasilare in the acuminated distichous leaves and almost excurrent nerve. In habit it much 
resembles H. denticulatum.

Has. Kerguelen’s Land ; both varieties, in the lake near Christmas Harbour (barren). 
With the habit of Fontinalis ; probably a distinct species, but the specimens are not in a state to be determined 
satisfactorily.

Haz. Strait of Magalhaens, D'Urville. Hermite Island; abundant everywhere in the woods. 
Closely allied to H. spiniforme, from which it chiefly differs in its broader leaves. 
6. Hypnum subbasilare, Hook.; Muse. Exot. t. 10. H. mnioides (ex errore), Schwaegr. Suppl. t. 257. 
Has. Hermite Island; in moist woods, at the roots of trees, very common, growing in tufts. 
This species so much resembles Æ. mnioides, as to be scarcely distinguishable from it until gathered, 
In our specimens the leaves are by no means bifarious, as stated in the Musci Exotici, and are compressed only 
when dry. The perichzetial leaves are erect, almost piliferous, and nerved to the apex; young calyptra coriaceous, 
slightly ventricose, not subulate, at length dimidiate. The operculum is absent from all our specimens. 
c. Foliis imbricatis ruptinervüs, seta laterali.
