Doubtfully distinct from R. hu^cinifcra. Probablv 

 only a robust form. 



Mt. Wellington. Tasman Peninsula.

s. 



Mad Ilia wey mouth iaiui , St. — Very pale. Leaves 



nearly rotundo-reniform to ovate, verv obtuse, patent, 

 overlapping the stem, imbricate, 0.8 mm. long, 0.7-1.0 

 mm. wide, ventral angle very decurrent ; ventral lobe 

 half as large as the leaf, taller than bread, quadrate 

 rotund, little inflated below, angle ottiise but often elon- 

 gated and recurved, more or less undulate; cells 10-18 ^.^ 

 trigones none, cuticle smooth. Perianth about 2 mm. 

 long, flat above mouth, broad entire. 



Vei*y distinct from other Tasmanian species in the 

 shape of the lobule. 



Tasman Peninsula. 



Radula irattsiaita, St. — Leaves ovate-elliptic with a 

 very obtuse apex, little imbricate, the dorsal margin only 

 slightly overlapping the stem, 1.2 mm. long, 0.8 mm. 

 wide, ventral angle decurrent; ventral lobe small quad- 

 rate inflated and convex, below angle very obtuse; cells 

 18 fi., surface convex, trigones none. Perianth linear 

 below, very flat and broad above, 3 mm., mouth crenate. 



Veiy like R. hiircinifero, but the leaves larger and 

 closer and the lobule more inflated and convex ; strongly 

 approaching R. pln/aoloha.

Radiihi aiievrysinat is, Tayl. — Verv small, amongst 

 other bi^^ophytes on bark. Leaves nearly rotund, 0.3-0.5 

 mm. long, very concave; ventral lobe rhomboid, inflated 

 nearly as large as the leaf, not appressed, angle acute; 

 cells 18 fx.. walls thin, trigones none, surface convex.

Frullania, Raddi. 



Closely creeping on bark or rock, pinnately branched, 

 often dark, sometimes green. Leaves closely imbricate, in- 

 cubous, rotund to reniform, entire, bearing near the ven- 

 tral base an appressed lobule in the forai of a water- 

 sack with the mouth pointing downwards, strongly curved 

 with a very oblique mouth to saccate with a straight 

 mouth. Underleaves rotund to obcuneate, apex more or 

 less deeply bifid. Bracts enlarged. Perianth oblong, 

 dorsally flattened to nearly cylindric, often with a strong
