22() TASMANIAN BRY^OPHYTA, 



R.S. TAS.. 



hexagonal. Seta short or long arising from the main: 

 stem; capsule inclined, equal, oblong; lid rostrate; exos- 

 tome teeth long, slender, endostome membrane rather deep, 

 processes long slender, gaping below ; cilia usually 2 

 slender. 



Thavmium pumilum (H.f. et W.). 

 Syn : Ixofhecium pmnihiin H.f. et W., Neckera rival is Mitt. 



Stems numerous erect dendroid, branches few, irregular, 

 equal or nearly so, about 1.5-2 cm. Leaves of branches in. 

 three rows, complanate, elliptic, acute 0.7 mm.; margin^ 

 irregularly serrate; nerve single vanishing about or above 

 the middle. 



On stones in streams. Slopes of Mt. Wellington. North 

 West Coast, etc. 



Lembophyllum Lindb. 



Rather robust- pinnately branched, but the branches in 

 some species long, irregular, vague. Lea.ves orbicular con- 

 cave, nerve indistinct or absent, cells usually oblong or 

 fusiform, rarely linear. Seta rather long smooth ; capsule 

 oblong ; lid conic. Exostome teeth lanceolate acute but 

 without filiform tips, bordered by a thin delicate mem- 

 brane ; endostome a short membranous base, processes per- 

 forate not exceeding the exostome, cilia usually two. 



Nerve none or very obscure. 



Cells linear cochl ear i folium. 



Cells fusiform cJandestinum. 



Nerve broad, cells oblong divuhinn. 



Leiidtoplnjlhim cocliJearifn] lum Schw. 



Stems suberect from a creeping rhizome, sub-dendroid or 

 vague, branches elongating 6-10 cm. complanate. Leaves 

 patent, not strongly imbricate, concave, very broadly ovate 

 with a very short, subacute, acuminate apex, 2 mm.; mar- 

 gin subserrate ; nerves 2, obsolete; cells all shortly linear 

 with obtuse ends, a small patch of brown cells at the angles. 



The specimen in Gunn's collection, identified by Mitten, 

 has no locality attached. It appears to be not at all com- 

 mon, but confusion has arisen through other mosses being 

 identified as this. Acroclndium chlamydophyUum, Wey- 

 inonthia mulle and Lemho2:)hyllnm clandestinum all appear 

 in collections under this name. 



Lemhophylhun rhnuhstlonnii (H.f. et W) Lindb. 

 Stems decumbent, elongated, branches erect simple or 

 divided rarely pinnate. Leaves nearly orbicular, very con- 

 cave, obtuse, patent imbricate, 1 mm.; margin closely ser-
