■Group D. Small plants with dispersed leaves. Capsule 

 ^mall, the base very shortly tapering or obtii&e; when fresh 

 the barren base or ajDophysis usually broader than the 

 spore-case. 



Base of capsule not obtuse. 



Nerve excurrent ... ovicarjmm 



Nerve lost in the apex to shortly excurrent. 



Margin plain Sullivan i 



Margfin subserrulate subcupulatum 



Nerve lost in the middle argenteum 



^ase of capsiule very obtuse. 



Margin not revolute. Nerve shortly excurrent. 



Border thickened, serrulate dlchotoimim 



Border plain ... cupulatum 



Margin revolute. Nerve boldly excurrent. 

 Leaves broad. Excurrent nerve 



shorter than lamina (/ambierense 



Leaves narrow. Excurrent nerve 



as long as lamina argillicola 



Bry 11771 Billardieri Schw. 



Medium sized, seldom exceeding 1 cm. Leaves clustered 

 at the apex, erect, broadly oblong to obovate-spathulate, 

 2-4 mm. ; margin with a conspicuous border of 3-4 series 

 •of linear incrassate cell&, revolute below, sharply serrate; 

 iierve shortly excurrent in bold cuspidate point. Cells 

 rather regularly rhomboid, rather thin-walled, averaging 

 ■55 X 20 A*. Seta 2 cm. Capsule cylindric, 4 mm., ba^e 

 very tapering, straight or curved, mouth little or not at all 

 constricted ; lid broad hemispheric with a central umbo. 



Common m grassy places, slopes of Mt. Wellington, Bruni 

 Island, Sheffield, etc. 



Bryum hrevimmidosum Hpe. 



Medium with short robust innovations under 1 cm. 

 Leaves rigid, numerous, erecto-patent, densely packed at 

 the ends, obovate-spathulate, 2.4 mm. ; margin with a broad 

 thickened border, revolute except towards the apex, where 

 it is sharply serrate; nerve rather strong, red, excurrent in 

 a short cuspidate point; cells rather regularly rhomboid, 

 averaging 25 x 11m. Seta 3 cm.; capsule clavate, 4 mm., 

 cernuous or pendulous, mouth not constricted, neck taper- 

 ing, but not long; lid pyramidal, umbonatc. 



Very similar to B. Billardieri, but more compact, leaves 

 anore rigid and cells only half as large. In some specimens
