100 MR. W. MITTEN ON THE MOSSES OE NEW ZEALAND, ETC. 



cucuUato-concavis rotundatis argute denticulatis marginibus ut in 

 caulinis spatiis angustis elongatis spiris repletis, poris nuUis. 

 Hob. Tasmania; Little Bridge's-head Creek, Mr. Archer. 



Habit intermediate between S. acutifolium and S. plumosum, but ap- 

 proaching more nearly to the latter. 



S. ANTARCTicuM (Mitten). S. cymbifolio simile, caule cortice e stratis 

 tribus cellularum inanium tecto, foliis ohlongis apice rotundatis, 

 margine nullo, spatiis intercellularibus latiusculis utplurimum fibris 

 repletis, ramulis patentibus, cortice cellulis inanibus, foliis late sub- 

 orbiculari-ovatis acuminatis inferne erectis superne patentibus apice 

 truncatis denticulatis margine angusto ex unico serie cellularum com- 

 posito spatiis latiusculis longitudine in folii medio latitudinem sex- 

 tuplo superantibus fibris spiris approximatis repletis, poris parvis sin- 

 gulis-quinisve, ramulis pendulis, foliis appressis ovatis integerrimis 

 spatiis quatuor, sex-poriferis.

 Hab. Campbell's Island. Dr. J. D. Hooker. 



Rather more rigid than S. cymbifolium, but closely resembling it in size 

 and appearance, differing, however, in the empty cortical cells of the stems 

 and the margined leaves of the rarauli. From S. compactum it differs in 

 the triple series of the cortical cells as well as in the form of the leaves. 



S. AUSTRALE [Mitten). S. cymbifolio simile, caule seriebus circiter 

 quinis cellularum corticato, foliis brevi-oblongis obtusis margine apicis 

 incurvo erosulo basi calcaratis immarginatis spatiis intercellularibus 

 inanibus, ramulis copiosis patenti-recurvis, cortice cellulis inanibus, 

 foliis imbricatis ovatis apice latiusculis obtusis margine ex uno serie 

 cellularum angustissimarum apicem versus remote minuteque serru- 

 lato, spatiis latis longitudine in folii medio latitudinem quadruplo 

 superantibus fibris spiris approximatis repletis, poris parvis singulis 

 quinisve, ramulis pendulis, foliis appressis ovato-lanceolatis obtusis, 

 spatiis majoribus, poris circiter quinis. 

 S. compactum Tar. ovatum, HooTc.fil. et Wils. FL Antarct. p. 122. 

 Hab. The Snugg, Huon, Mr. Oldfield ; and in Campbell's Island, Dr. J. 

 D. Hooker. 



Very similar to S. cymbifolium and to S. antarcticum, but in structure 

 allied only to the latter, from which it recedes in the form of its branch 

 leaves. S. compactum is immediately distinguished from these species 

 by its cortex being composed of a single series of ceils. 



S. cymbifolioides, C. Mutter, Bot. Zeit. 1851, p. 546. 

 Hab. Cheshunt, Tasmania, Mr. Archer. 



The description above quoted, according to Mossman's specimens, is 

 incorrect, for the cauline leaves have a margin of three rows of narrow 

 cells. In this species the cortical cells are in a single stratum, and the 

 leaves of the ramuli have the intercellular spaces with a pore between 

 every turn of the spiral fibre.
