2 new or rare species of tasmanian hepatic^. 



Lepidozia capillaris (Sw.) vae. geniculata. 



[Lepidozia geniculata Pears. Mss.] 



Densely caespitose, flagelliferous, gracile, small (2), scandent, 

 olive-brown ; stems irregularly bipinnate, rigid ; leaves subtrans- 

 verse, approximate teeth inflexed, geniculate, palmately-quadrifid 

 to I their length, -with, a spur at one or both basal angles ; under- 

 leaves large, ovate, quadrate, trifid, rarely quadrifid ; inflorescence 

 9 on short postical branches ; bracts oblong-oval or ovate-acute, 

 apices bidentate, margins sparingly dentate ; perianth very long 

 and narrowly cylindrical, composed of one layer of cells, trigonous, 

 mouth laciniate-ciliate. 



DioicoTis ? Densely caespitose, erecto-precumbent, flagelli- 

 ferous, flagella postical, leafless, radicellose, minute, yellowish 

 olive-brown. Stems irregularly bipinnate, rigid, apex re- 

 curved, a cross section showing 12 large, quadrate, dark- 

 walled cortical cells, interior ones smaller, hyaline, 6 and 7 

 cells in diam. The young branches appear with the leaves 

 to be frontally compressed. Leaves transversely inserted, 

 crowded above, approximate or loosely imbricated, and 

 slightly incubous on the lower part of the stems, geniculate, 

 basal portion patent, teeth erect or inflexed, sub-verticellate, 

 when flattened out palmately-quadrifid, with a short spur on 

 one, very rarely on both basal angles, much rarer still an 

 additional smaller one is present ; branch leaves trifid, 

 segments fths of the leaf long, subulate (at apex one cell, 

 at base 3 and 4 cells broad and 10 to 12 cells long) ; entire 

 portion of leaf 4 cells deep ; cells minute, guttulate, sub- 

 quadrate or oblong-quadrate. TJnderleaves large, breadth of 

 stem at base, ovate or oblong-quadrate, trifid, sometimes 

 quadrifid, on terminal branches often bifid. Involucre 

 cladocarpous, postical, branches short. Bracts oblong-oval, 

 ovate-acute, apex bidentate, margin sparingly denticulate or 

 with two acute teeth. Perianth very long, half the length of 

 the whole plant, narrowly cylindrical, very delicate texture, 

 composed of a single layer of cells, 40 to 50 cells in circum- 

 ference, upper portion trigonous ; mouth laciniate-ciliate, 

 about 15 cilia, 2-4 single cells long, 2-3 cells broad at the 

 base. Pistillidia few.
