" Monoicum, habitu P. alternifolii, gracile, fohis inferioribus 

 e basi ovaH subulato-lanceolato-acuminatis, nervo subulam

 parallelogrammaticis superioribus minoribus, perichsetiahbus 

 thecam non tegentibus, patuhs anguste elhpticis subulato longe 

 attenuatis cauahculatis apice parce denticulatis integerrimisve 

 laxe areolatis, theca in pedunculo brevi subglobosa leptodermi, 

 operculo brevissimo, caiyptra cucullata ad thecee mediam de- 

 scendente. Hah. Tasmania and King George's Sound. Ex- 

 cepting that the perichtetial leaves are less straight and 

 bristly, in general appearance scarcely different from P. alter- 

 nifolmm, but its leaves are of a different form." — W. Mitten,
