110 TASMANIAN BRYOPHYTA, 



Zoopsis, Hook. f. et Tayl. 

 Stems slender decximbent with few iiTegular ventral 

 branches, a narrow central strand of elongated narrow cells 

 surrounded by a cortex of large inflated cells. Leaves more 

 or less rudimentary^ reduced to the base or deeply bifid. 

 Underleaves rudimentary. Fertile branch short arising 

 from the ventral surface ; perianth terminal oblong to 

 fusiform, smooth or plicate, mouth tapering lobed. 



Colour always pale watery green. The genus is most 

 closely allied to Lepidozia. Z. leitgch'unia might readily 

 be refeiTed tO' that genus. 



Leaves reduced to 2 celled lobes argentea 



Leaves rudimicntary with 2 spinous lobes... setulom, 

 Leaves with 2 unequal lobes Jeifgehiana 



Zoopsis argentea^ Hf. et Tayl. — Shoot a flat linear 

 frond. Leaves reduced to alternate lobes each of two in- 

 flated cells; underleaves rudimentary formed of two oblong 

 cells and two much smaller apical ones. Bracts and bracte- 

 ole small bifid : perianth narrow pyriform-cylindric, 

 divided above to a third of its length into six lanceolate 

 acute lobes. 



Common on dead wood. 



Australia. New Zealand. Indian Archipelago. 



Zoopsis setulosa, Leiig. — Shoot a flat linear frond. 

 Leaves reduced to alternate lobes of two large inflated cells, 

 each cell tipped with a linear two-celled lobe; underleaves 

 rudimentary of two short basal and two linear upper cells. 

 Bracts bifid, apex setulose, bracteole similar, perianth ovate 

 plicate, mouth deeply six lobed, lobes setulosie. 



Mt. Wellington. Cradle Mt. West Coast. 



Zoopsis leitgehiana, C. et P. — Shoots slender. Leaves 

 remote, unequally bifid, base 1 cell deep, 4 cells wide, 

 dorsal lobe 3 cells in one seiies, ventral lobe 5 cells long, 2 

 cells wide at base; underleaves of 2 oblong cells, tipped 

 each with a small cell. Bracts and bracteole l-3rd bifid, 

 lobes acute; perianth linear triplicate, apex shortly 6 lobed. 



Kingston. West Co^ast. 



East Australia. New Zealand. 



IsoTACHis, Mitten. 



Decumbent, stem elongating with few irregular 

 branches. Leaves incubous to transverse, squarrose to 

 decurvo-homomallous, conduplicate concave, asymmetric, 

 apex usually truncato-bilobed, lobes broad short unequal, 

 dorsal margin more expanded than the ventral, insertion
