124 TASMANIAN BRYOPHYTA, 



both sides with the leaves reflexed oblong-quadrate, rather 

 longer than broad apex irregularly dentate. 



Very common. 



East Australia. 



Bazzania involnta (Mont.). — Leaves broadly ovate 

 falcate decurved, 1.5-2 mm. long, apex narrow with 3 short 

 acute diverging teeth, sometimes with a few serrations 

 intermixed, upper cells 15-18 ju., walls thick, lower 30-45 

 fx., trigones rotund ; underleaves nearly reniform 2-3 times 

 as broad as long, apex erose-dentate, reflexed, shortly con- 

 nate on both sides, upper cells often larger and hyaline. 



Very common in forests. 



New Zealand. Fuegia. 



Form, elegans, B. elegans, Col. — Regularly forked ; 

 leaves very close and regularly spreading. 

 Hartz Mt. 



Bazzania adneora (L. et L.). — Leaves not as strongly 

 deflexod as in allied species, broadly ovate, falcate 2 mm. 

 long, dorsal base broadly overlapping the stem, apex trun- 

 cate ti'identate, teeth acute, they and the upper portions 

 of the margins a,rmed with few small acute serrations, 

 when growing in deep shade the leaves are shorter and 

 serrations less marked ; when growing on firm bark the 

 flagella creeping and bearing leaves similar to those of the 

 stem only smaller and nearly entire; cells 18 //., with 

 thick walls, trigones large acute ; underleaves quadrate 

 broader than long, apex erose- dent ate, upper cells large 

 hyaline, base shortly connate with the leaves, slightly 

 reflexed. 



Some forais approximate to B. invoJuta. 



Very common. 



New Zealand. South Africa. 



Bazzania haileyana, St. — Very similar in habit to B. 

 adnexa, but leaves still less decurved, less rigid and nar- 

 rower, dorsal base lesr- expanded, 1.5-1.7 mm. long, apex 

 truncate with three sharp diverging teeth more or less 

 armed with short sharp serrations ; underleaves nearly free 

 reflexed, more rotund than quadrate, twice as broad as the 

 stem. 



Very close to B. adnexa and probably not always 

 separable. 



Adamson Peak.
