280 TASMANIAN HEPATIC^. 



short. Male receptacles on separate plants on shorter 

 peduncles, orbicular, 4-lobed ; lobes crenate ; anthers 

 in 8 radiating lines. Syn. Hep. 525, M. J>olymorpha, 

 M. Antarct. 168 and 446, not of Linnseus. PL xxxiv, 

 sxxv. 



Marchantia polyniorpha, Linn., is stated by Dr. 

 Gottsche in " Plantse Muellerianse " to occur in Tas- 

 mania, but all the specimens yet observed appear 

 to belong to 'M. tahularis, Nees, which differs more 

 in appearance than in any decided character from the 

 European species.

M. piLEATA, Mitten, in Fl. N.Z. ii., 169. Frond Sin. long, 

 glaucous green, jin. broad, dichotomous, linear, flat, 

 smooth ; pores minute, margined with white ; margins 

 entire; underneath dark purple. Female receptacle 

 sub-eccentric, hemispherical, tuberculate, naked below, 

 margin crenate ; peduncle i-in. long, smooth, purple ; 

 margin of the involucres torn. Male plant, receptacle 

 on short peduncle, 4-5 lobed, orbiculate, obtuse. 



The latter peduncle 2-3 lines long, sealed at the 

 base ; receptacle 2 lines wide, margin crenulate. 



Only one female receptacle has been seen which has 

 the peduncle inserted either in or very near its centre ; 

 it is hemispherical. The plant referred to this species 

 corresponds so nearly in the size, colour, and areola- 

 tion of its fronds that thei'e seems little reason to 

 doubt its being the male of that described as above 

 from Fl. N.Z. PI. Tasm. ii., 240, n. 



On the ground with M. tabularis, Hooker, Archer. 



3. M. EOLiACEA, Mitten in Fl. N.Z., 168. Frond 2-3in. 

 long, subcariaceous, flat, smooth, glossy above ; pores 

 small, pale : below deep purple ; margin entire, undu- 

 late. Female receptacle eccentric, convex, umbovate, 

 about 8-lobed; peduncle lin. long, with purple scales; 

 lobes dilated, foliaceous, sub-crenate ; involucres pale, 

 lacerate, ciliate. Cups with gemmae, funnel-shaped, 

 with toothed ciliate margins. 



The surface of the frond is nearly as glossy as that 

 of M. nitida of New Zealand.
