1. Andeejea, Uhrh. 

 A. subulata, Harvey. 



Hab. Tasmania ; Jackey's Plain Creek, on rocks ; rivulet at the back 

 of Cumming's Head, Western Mountains. Mr. Archer. 



A. nitida, Hook.fil. et Wils. 



Hab. Tasmania; on stones; rivulet near Cumming's Head, Western 

 Mountains. Mr. Archer. 



A. petrophila, Ehrh. 



Hab. Tasmania; the Falls. Mr. Archer. 



A. acuminata (Mitten). A. acutifolice simillima, fohis e basi erecta 

 caulem amplectente patulis apicibus incurvis explanatis ovato-lanceo- 

 latis margine partis erectae minute crenulata dorso apicem versus 

 inconspicue papillosis, cellulis ex apice ad medium minutis quadrato- 

 rotundatis diametro circiter j^Vo unciae metientibus deinde in ob- 

 longas subparallelogrammaticas parietes latitudine superantes infeme 

 in longiores angustas fuscidulas parietibus crassioribus transeuntibus, 

 perichsetialibus ovalibus tenuiter acuminatis convolutis. 

 Hab. Tasmania ; Cheshunt. Mr. Archer. 



Very nearly allied to A. acutifolia, but with leaves a little wider, and 

 cells in the upper portion smaller and more numerous, all with much 

 narrower walls ; those just below the middle of the leaf with walls nar- 

 rower than their own width, and pellucid. From A. petrophila it re- 

 cedes in the form of its leaves as well as in their cellular structure 

 already described. 



A. MONTANA {Mitten). A. alpincB simillima, foliis parte superiore sen- 

 sim acutis vix acuminatis margine integerrimis, margine partis inferi- 

 oris minute crenulato, cellulis basi oblongis elongatisque parallelo- 

 graramaticis cito in minutas longitudine 2oVo> latitudine j oVo unciae 

 metientes transeuntibus. 



Hab. On rocks ; rivulet behind Cumming's Head, Western Mountains ; 

 Tasmania. Mr. Archer. 

 Closely resembling A. alpina in size, habit, colour of its leaves, and 



general appearance ; but the outline of its leaves, when compressed, is 



ovate, slightly acuminate; the cells at the base distinctly parallelo-
