intense purpureas, margine integerrimo repande-undulato. Pedunculus polliearis, ramentis squamisque purpureis ob- 

 tectus. Receptacnlum- fwmineum convexum, poris albido-limbatis punctatum ; lobis latissimis, subcrenatis. Scyphi 

 infundibuliformes, marginibus ciliato-dentatis, gemmulas lentiformes includentes. 



A larger species than M. nitida. Allied to M. disjuncta, Sullivant, from the United States, in the broad and 

 leafy lobes of its female receptacles, but the fronds of the latter are less coriaceous and opaque. In M. foliacea the 

 surface of the fronds is nearly as glossy as that of M. nitida. 



4. Marchantia macropora, Mitten; receptaculo foemineo excentrico hemisphaerico sub-5-lobo verru- 

 coso lobis bipartitis, involucris margine purpureis laceris, fronde lineari dichotoma, poris magnis purpureo- 

 lirnbatis. 



Hab. Northern Island : wet banks, Makororo river, Ahuriri, etc., Colenso. Auckland, Sinclair. 



Frondes sordide virides, 1-2-pollicares, 2 lin. lata, margine piano integerrimo, subtus atro-purpureae, medio 

 radicellis vestitse. Squama paucse, obtusas. Fori maximi, fusco-purpurei, remoti. Receptacnlum fwmineum sub- 

 hemisphaBricum, verrucis tumidis apice porosis asperum. Involucra basi iaciniis lanceolatis purpureis vestita. Pe- 

 dunculus semipollicaris, Iaciniis paucis lanceolatis paleaeeus. 



At once distinguished from its allies by its large purple or brownish pores, and the tumid warts of its female 

 receptacles, which have each a large purple-mouthed pore. 



5. Marchantia pileata, Mitten; receptaculo foemineo subexcentrico hemisphaerico tuberculis brevibus 

 ruguloso margine crenato, involucris margine laceris, fronde dichotoma, Iaciniis linearibus planiusculis laevi- 

 bus, poris minutis. 



Hab. Northern Island : wet banks, Makororo river, Colenso. 



Frondes glauco-virides, tripollicares, 3 lin. latae, integerrima?, subtus atro-purpurese. Fori minuti, albido-mar- 

 ginati. Pedunculus semipollicaris, lseviusculus, atropurpureus. Receptacnlum fwm. 2 lin. latum, subtus nudum. 



A larger species than M. viridula, Lehm. et Ldbg., and with more linear fronds than M. nitida, to which they 

 approach more nearly in the appearance of their surface. Only one female receptacle has been seen, which' has the 

 peduncle inserted either in, or very near its centre j it is hemispherical, and not so conical as that of M. Brasiliensis 

 or M. cartilaginea. The latter species, although stated in the 'Synopsis Hepaticarum' to be from St. Vincent's, 

 is marked "Nepal" in Herb. Hooker, and is mixed with Bartramia Turneriana, Schw.

In the absence of fructification, the New Zealand specimens cannot be distinguished from those from various 

 other parts of the world. The size is certainly very much greater, but this character cannot be depended upon hi 

 these plants. Also a native of Lord Auckland's Group,
