series of forms running through Jin^f/. Mneller'i, Noes, Jimg. acuta, 

 Lindenb. to Jung, furbinafa, Eacldi. at the other extreme, which 

 all agree in their dioicous inflorescence, but the variation in size. 

 shape of leaf, stipule and perianth differ to a very great extent ; 

 for further notes see under the varieties following. 



Distinpruished from var. Muelleri, Nees, bv its larger size, 

 more lax habit, more quadrate leaves, with shallower and broader 

 sinus. 



From HarjiantliUH Flotowii, Nees, by its smaller stipules and 

 terminal perianth. 



From Jungermania venfricosa, Dicks., which is also dioicous,
