margine minutissime eroso cellulis basi pro spatio brevi elongatis mox 

 in rotundatas transeuntibus papillosis apicem versus obscurioribus, 

 perichaetialibus brevioribus duplo latioribus acutis, theca in pedunculo 

 tri-quadrilineari elongate ovali sub ore intensius colorato plicata, peri-

 Hab. On trees, Cheshunt, Tasmania, Mr. Archer ; on dead branches 

 of trees, Kermandec Rivulet, Mr. Oldfield. 



Fulvous ; in size and general appearance scarcely different from 

 M. hemitrichodes, to which at least in part belongs M. amm7iumf Horn- 

 schuch, according to authentic specimens'; but in the present, the leaves, 

 although agreeing in form, have their cells more widely separated, rather 

 larger, and not obscure, as in M. hemitrichodes, in which too the leaves 

 are smoother. 



M. ORTHOPHYLLUM {Mitten). Dioicum, M. longirostri habitu statura 

 coloreque simile, foliis siccitate appressis strictis madore patentibus 

 late lanceolatis breviter apiculatis nervo excurrente concolori carinatis 

 margine integerrimo cellulis e basi ad medium elongatis angustis inde 

 ad apicem ovoideis latitudine circiter ^oVo uneiae metientibus, peri- 

 chaetialibus longioribus latioribus erectis longiore apiculatis, theca in 

 pedunculo circiter sex lineari ovali ore plicato, collo sensim attenuate, 

 operculo subulato subaequilongo, peristomio simplici dentibus brevibus 

 liberis, calyptra nuda.

Very distinct from all its congeners in the leaves being straight, and, 



except that they are appressed to the stem, unaltered in drying. 



M. Mossmannianum (C. Miiller, Bot. Zeit. 1851, p. 561) is identical 

 with M. gracile. Hook.

 L. repens (Anictangium, Hook. Muse. Exot.). 

 Hab. Tasmania, Port Sorrell, and north side of Cataract, Launceston, 



Mr. Archer. 



This curious moss, which has no affinity with Hedwigia nor with 

 Erpodium, seems to accord very nearly with Dr. Montague's description 

 of L. Perrottetii from Senegambia, and from the structure of its leaves 

 appears to be more nearly allied to this family than to any other. 



3. Phtscomitrium, Bri<^. 

 P. coNicuM (Mitten). P. pyriformi simile, foliisque conformibus ser- 

 rulatis cellulis fere dimidio minoribus marginalibus intensius coloratis.
