100 MR. W. MITTEN ON THE MOSSES OF NEW ZEALAND, ETC. 
cucullato-concavis rotundatis argute denticulatis marginibus ut in 
caulinis spatiis angustis elongatis spiris repletis, poris nullis. 
Hab. 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). 5. cymbifolio simile, caule cortice e stratis 
tribus cellularum inanium tecto, foliis oblongis 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. 
S. compactum, var. Hook. fil. et Wils. Crypt. Antarct. p. 122. 
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 ramuli. 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, 
folis 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 var. ovatum, Hook. 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 cells. 
S. cymbifolioides, C. Müller, 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.
