Var. 4, from the lax texture of the foliage, resembles $. acutifolium, but the stem has a single layer of cortical 
cellules as usual. Var. 3 has a singular aspect, and may perhaps be a distinct species, with purplish foliage. 
5. Sphagnum molliculum (Mitten, in Linn. Soc. Journ. ined.); “8. plumoso simile, caule cortice 
ex strato unico cellularum formato, foliis subelliptico-ovalibus basi brevissime calcaratis apice rotundatis 
subtruncatis minute denticulatis spatiis intercellularibus ut plurimum repletis margine e serie triplici cellu- 
larum angustissimarum composito, ramulis flaccidis cortice cellulis inanibus foliis ovatis acuminatis mar- 
ginibus superne incurvis apice cucullato-concavis rotundatis argute denticulatis marginibus ut in caulinis 
spatiis angustis elongatis spiris repletis poris nullis ?” 
Has. Cheshunt, Archer. 
* Habit intermediate between S. acutifolium and S. plumosum, but approaching more nearly to the latter.” — 
Mitten, 1. c. 
6. Sphagnum cymbifolioides (C. Mueller, Bot. Zeit. 1851, p. 546); “caulis procerus flaccidus, 
ramis subremotis breviusculis cuspidatis curvatis patentibus vel recurvatis, comalibus erectis brevioribus 
densiusculis obtuse cuspidatis; folia caulina e basi latissima plana ovalia, apice involutaceo obtuso brevi, 
haud truncata, e cellulis breviusculis basi laxioribus longioribus, ductibus subheteromorphis preditis, 
ubique fere repletis reticulata, immarginata, e ceteris rameis similia; ramea ovalia apice haud involuta, 
erecto-appressa nec faleata nec secunda, summo apice truncato dentibus circiter octo coronato, tenuiter 
marginata, e cellulis teneris amplis flexuosis valde repletis constructa; cellule ramorum inanes."—

“ 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.” —Mitten, 1. c. 
7. Sphagnum confertum (Mitten, in Journ. Linn. Soc. ined.) ; “habitu 8. compacti, ramulis dense 
confertis breviusculis, caule cortice e serie cellularum triplici formato serie externa fibris repleto, foliis 
oblongis apice rotundatis suberosulis spatiis intercellularibus superioribus fibris repletis inferioribus inani- 
bus margine nullo, ramulis cortice cellulis inanibus foliis ovatis concavis obtusis apice truncatis denticulatis 
margine serie unica cellularum angustissimarum superne minutissime serrulato spatiis latiusculis fibris spiris 
approximatis repletis poris singulis.” 
Has. Rivulet near Cumming’s Head, Western Mountains, Archer. 
* Appearance and habit similar to 9. subsecundum, but the cortical cells disposed in a triple series.” —
