F . tasjuan/ca, St., differs in the appendage, being long, 

 with a slender bifid apex, but the character appears in-

Marchantia, L. 



Large, fleshy, repeatedly forked, closely decumbent. 

 Dorsal surface marked into lozenge-shaped areolae, each 

 with a central pore opening into an air chamber; pores in 

 perpendicular section barrel-shaped, formed of about four 

 series, of cells ; external orifice surrounded by 4-6 concen- 

 tric rings of narrow cells ; internal orifice cruciate, or 

 nearly quadrate in Tasmanian species. Carpocephalum 

 with a long stalk, with twO' rhizoid-bearing grooves ; head
