Gen. XXVI. MARCHANTIA, Linn. 
l. Marchantia tabularis (Nees ab E.). 
Has. Tasmania; very common in wet shady places, where there have been fires, but also frequent 
even on the tops of the hills, Gunn, J. D. H. Back River Gully, Oldfield. Hospital Bay, South Huon, 
Oldfield ; elsewhere, Archer. 
Marchantia polymorpha, Linn., is stated by Dr. Gottsche, in * Plante: Muellerianz,' to occur in Tasmania, but 
all the specimens yet seen appear to belong to M. tabularis, Nees, which differs more in appearance than in any 
decided character from the European species. 
2. Marchantia pileata (Mitten, in Fl. N. Zeal. p. 169).—Additur descriptio plantæ masculæ :— 
receptaculo masculo brevipedunculato orbiculato obtuse quadri-quinquelobo. 
Haz. On the ground, with J/. tabularis, J. D. H., Archer. 
Pedunculus bi-trilinearis, basi squamosus. Receptaculum latitudine bilineare, margine crenulatum. 
The un referred to this Ben corresponds so nearly in the size, colour, and areolation of its fronds, that 
there seems little reason to doubt its being the male of that already described in the * Flora of New Zealand.” 
9. Marchantia foliacea (Mitten, in Fl. N, Zeal. p. 168). 
Has. Tasmania, Archer.
