128 TASMANIAN BRYOPHYTA, 



or many cilia chiefly along the ventral margin, dorsal lobe 

 similar two-thirds as large; cells rectangular 24 x 45 ytt., 

 walls equal thin, trigones none, lower cells much larger; 

 underleaves half as large as the ventral lobe, reniform, 

 deeply quadrifid, armed with long cilia. 



Very common on clay banks. 



Australia. New Zealand. 



F(>r>n. yduculvntcid. — Leaves entire or with few broad 

 irregular teeth, dorsal lobe \ ventral ; underleaf oblong 

 one-fifth bifid with few lateral broad teeth. 



Balantiopsix (t(^(i}i ilohn , Berg. — Very close to the last 

 in all details. Dorsal lobe as broad as the ventral but 

 shorter; underleaves oblong, l-3rd bilobed armed with 

 numerous cilia to deeply 4-lobed. Both species as found 

 in Tasmania vary and run into one another. This descrip- 

 tion applies to a plant determined by Stephaiii. It is 

 doubtful if we possess the typical form.

New Zealand. 



SCHISTOCHILA, DuM. 



Plants robust, stems simple or with few irregular- 

 branches, thick fleshy, often bearing paraphylls between 

 the leaves. Leaves two lobed, the dorsal smaller than, 

 or often nearly equal to, the ventral, attached by nearly 

 the whole of its length to and within the margin of the 

 ventral lobe, the dorsal margin of the ventral lobe then 

 forming a single wing, or joined by a commissure from the 

 adjacent surfaces, and then both margins free, forming a 

 double wing. Sporophyte terminal deeply sunk in the axis, 

 the calyptra immersed in large bracts, some of which are 

 attached to it. No perianth.
