1. ANDREASA, Ehrh. 
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. 
А. petrophila, Ehrh. 
Hab. Tasmania; the Falls. Mr. Archer. 
A. ACUMINATA (Mitten). A. acutifolie simillima, foliis e basi erecta 
caulem amplectente patulis apicibus incurvis explanatis ovato-lanceo- 
latis margine partis erecte minute crenulata dorso apicem versus 
inconspicue papillosis, cellulis ex apice ad medium minutis quadrato- 
rotundatis diametro circiter тууу uncie metientibus deinde in ob- 
longas subparallelogrammaticas parietes latitudine superantes inferne 
in longiores angustas fuscidulas parietibus crassioribus transeuntibus, 
perichetialibus 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. alpine simillima, foliis parte superiore sen- 
sim acutis vix acuminatis margine integerrimis, margine partis inferi- 
oris minute crenulato, cellulis basi oblongis elongatisque parallelo- 
grammaticis cito in minutas longitudine убу, latitudine тууу unciæ 
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- :
