238 TASMA.NIAN BRYOPHYTA, 



R.S. TAS. 



endostome 16 rather bold acute processes arising from a 

 short-base, as long as the exostome. 



Often treated as a sub-genus of HijiJo pterygium. 

 Lophidium palJens H.f. et W. 



Stems erect copiously branched, 10-12 cm., branches and 

 lateral leaves complanate. Lateral leaves ovate-oblong, 

 apiculate, 1.8 mm.; margin bordered, serrate in the upper 

 part; nerve vanishing at the apiculus ; ventral leaves much 

 shorter, ovate nerve running through the longer apiculus. 

 Seta straight or curved 5 mm.; capsule 1.8 mm., lid nearly 

 as long. 



Common on bark of trees in forests. 



Mt. Wellington, Tasman's Peninsula, Maria Island. 



Hypopterygium Brid. 



Stems erect, short, dendroid, branches in an irregular 

 terminal fascicle. Leaves trifarious, those on the stem 

 equal, on the branches complanate ; two lateral rov/s dis- 

 tichous ; nerve vanishing above the middle ; cells rather 

 large rotund ; ventral row smaller, appressed. Seta erect, 

 arising just above or about the lower branches ; capsule 

 pendulous, pyriform with a constricted neck or broadly 

 oblong; mouth broad; peristome of 16 bold lanceolate 

 teeth ; endostome same length, lower third membranous 

 with 16 perforated processes. Lid rostrate. Calyptra long 

 with a short mitriform base. 



Hypopterygium novae -zel and iae CM. 



Stem 2 cm.; branches 1-1.5 cm., yellow green. Lateral 

 leaves patent, distichous, ovate acute, 0.8 mm.; margin 

 bordered, acutely serrate above; ventral leaves rotund, 

 much smaller, the nerve excurrent. Seta 1 cm. ; capsule 

 broadly oblong, pale brown, granular, 2 mm. ; lid very 

 long, curved usually exceeding the capsule. 



Slopes of Mt. Wellington, Gordon, Interlaken. etc. 



Catharomnion H.f. et. W. 



Erect or depressed ; stems elongated, bristly, pinnately 

 branched or the branches falsely fasciculate. Lateral leaves 

 oblong, complanate, bordered with long cilia; nei^ve slender 

 vanishing alDOve the middle; cells regularly hexagonal to 

 rhomboid ; ventrals very small. Seta rather short ; cap- 

 sule oblong, suberect ; lid rostrate ; calyptra mitriform, 

 inflcxed and laciniate at the base. Exostome absent; 

 endostome processes subulate, papillose connected at the 

 base by a very short membrane. 



Close to Hypopterygium.
