TASMANIAN BRYOPHYTA, 



Flagiochila microdictyum, Mitt. — Small, simple, rarely 

 exceeding 5 cm. Leaves crowded, shaped as in F, 

 deltoidea, about 2.5 mm. long and rather broader, apex 

 and ventral margin undulate, nude or rarely a few irre- 

 gular or many very small teeth; cells 20 fx , trigones as 

 large as the cells, walls sinuous. 



Mt. Wellington. Adamson Peak. New Zealand. 



PhifjiochiJa fa^ciculata, Lindh. — Usuall}^ tall, slender, 

 and freely branched. Leaves imbricate, obliquely ovate; 

 trigonous or rather oblong, 2-3 mm. long, dorsal margin 

 nearly straight and nude below, ventral margin boldly 

 curved from apex to base, and armed with few or many 

 spinous teeth; cells averaging 20 ;x,. trigones rather small. 

 Perianth hardly exserted, mouth truncate, coarsely spin- 

 ous. 



Distinguished from F. deltoidea by the smaller, nar- 

 rower leaves. 



Very common. 



New Zealand. Auckland Island. East Australia. 



Flagiochila s<tromhi folia. {Taylor), Lehm. — Usually 

 robust and branched. Leaves obliquely ovate, with an 

 obtuse apex, about 2.5 mm. long, dorsal margin nearly 

 straight, lightly reflexed, nude, ventral margin expanded, 

 but not extremely so, armed with short, broad acute teeth ; 

 cells 27 IX.. walls rather thick, trigones medium. Perianth 

 shortly exserted, mouth rotund, armed with spinous teeth. 



The straight dorsal margin distinguishes it from the 

 last; the smaller more ovate leaves from F. deltoidea. 



Very common. 



Flagiochila lyallii. Mitt. — Usually tall and branched. 

 Leaves not crowded, obliquely ovate, 1.5-2 mm., dorsal 

 margin lightly curved, usually with a few bold teeth, ven- 

 tral margin more strongly curved, but not ampliate, armed 

 with strong, broad spinous teeth ; cells about 16 /x. ; 

 trigones small or none. Perianth shortly exserted, mouth 

 very broad and armed with spinous teeth. 



Less crowded leaves, narrower apex and fewer teeth 

 mark its distinction from F. fasciculata. 



Very common. 



New Zealand. 



Flagiochila fuf^cella, TTf. rt r.— Rather small for the 

 genus, seldom exceeding 3 cm., usually many branched. 

 Leaves with a nearly transverse very narrow insertion, 

 subrotund, 3 mm. long, dorsal margin curved, slightly 

 deflexed, nude, apex and ventral margin very broadly
