162 FLORA OF TASMANIA. [Musci, by W. Wilson. 
SUBORDER 2. SPHAGNACEE. 
Gen. II. SPHAGNUM, I. 
Theca globosa, in receptaculo exserto sessilis, stomate nudo exannulato. Calyptra medio rupta, basi 
persistente. Pructificatio axillaris. 
1. Sphagnum cymbifolium (Dillen. Hist. Muse. t. 32. f. 1); caule robusto elongato, ramis con- 
fertis brevibus tumidis, foliis rotundo-ovatis concavis obtusis apice dorso muricatis, utriculis (cellulis ramu- 
lorum externis) spiraliter striatis.—Bridel, Bryol. Univ. Sphagnum obtusifolium, Hook. et Tayl. ex parte, 
var. condensatum. (Gunn, 1.) 
Has. Western Mountains, elev. 3000 feet, in bogs, Gunn, 1578; swamp, New Norfolk, Oldfield, 62, 
J. D. H.; Cheshunt, Archer. 
DisrRrB. Europe, and all parts of the world. 
2. Sphagnum compactum (Brid. Sp. Muse. i. 18, et Bryol. Univ. i. 16); caule robusto, ramis 
dense approximatis patentibus crassis strictis, foliis rameis imbricatis ovato-oblongis concavis apice subin- 
flexis truncatis denticulatis.—Nees e? Hornsch. Bryol. Germ. t. 2. f. 5 
Var. y. ovatum ; foliis brevioribus ovatis subacutis. 
Has. In bogs: Huon River, Oldfield, 61. 
DisrarB. Campbell's Island, New Zealand. The ordinary form of the species frequent in Europe and 
in North America. 
The var. y much resembles S. cymbifolium, but the leaves are not muricate at the dorsal apex, and the utricles 
-of the branches are destitute of spiral strie. Foliage of a pale fawn-colour. 
3. Sphagnum australe (Mitten, in Linn. Journ. ined.); “8. cymbifolio simile, caule e seriebus 
circiter quinque cellularum corticato, foliis brevi-oblongis obtusis margine apicis incurvo erosulo basi calca- 
ratis immarginatis spatiis intercellularibus inanibus, ramulis copiosis patenti-recurvis, cortice cellulis inani- 
bus foliis imbricatis ovatis apice latiusculis obtusis margine ex una serie cellularum angustissimarum apicem 
versus remote minuteque serrulato spatiis latis longitudine, in folii medio, latitudinem quadruplo superanti- 
bus fibris spiris approximatis repletis poris parvis singulis quinisve, ramulis pendulis foliis appressis ovato- 
lanceolatis obtusis spatiis majoribus poris circiter guinis.”—S. compactum, var. ovatum, Hook. fil. et Wils. 
Fl. Antarct. p. 122. 
Has. Huon River, Oldfield. 
DisrRrB. Campbell’s Island. 
“ Very similar to 8. cymbifolium and to S. Antarcticum, but in structure allied only to the latter, from which it 
recedes in the form of its branch-leaves. 8. compactum is immediately distinguished from these species by its cortex 
being composed of a single series of cells.” —Mitten, 1. c. 
4. Sphagnum contortum (Schultz, Suppl. Fl. Starg. 64); caule elongato rigidiusculo, foliis ovato- 
lanceolatis imbricatis acutis concavis subcoriaceis. (Oldfield, 29.) 
Var. 2. /azum ; ramulis distantibus attenuatis patulis. (Gunn, 41.) 
Var. 3. scorpioides ; ramis dense confertis singulis binisve brevibus patentibus sursum curvatis, foliis 
elongatis apice preemorsis, rameis erectis subsecundis. (Gunn, 2 
Var. 4. intermedium ; caule humili, ramulis dense confertis attenuatis, foliis laxer eticulatis. ( Gunn, 3.) 
Has. In bogs. Vars. 1 and 3. Mount Wellington, and the others common. 
Disrris. Europe.
