258 LIST OF THE MUSCI AND HEPATIC^ 



mately allied to the original species ; besides which there should be 



added JFeissia crispula, Hedw., W. compacta^ Schw., W. fastigiata, 

 Taylor, W. torti/olia. Hook, fiL et Wils., TF. pomiformis. Hook., 

 Syrrhopodon Dregei, Hsch.j and S, clavatus, Schw., all agreeing closely 

 in habit and in the structure of their leaves and fruit ; from Weissia^ 

 as represented by 7F, controversa^ they recede in the cell-structure of 

 the leaves, which approaches very nearly to that of Bicranum^ without 

 however having the glossy appearance usual in that genus. 



2. POTTIOIDE^. 



cylindricum 



16. Weksiafavipes, Hook. fil. et Wils. (No. 60,-77, 1855.) 



17. Desraatodon nervosus, B. et S. (No. 132, — 41, 146, 1855.) 



18. D. adustuSy Mitten ; dioicus, caule gracili ramoso, foliis paten tibus 

 ovatis acutis concavis margine maxime revoluto, nervo crassiusculo 

 excurrente, dense papillosis, perichaetialibus latloribus tenuioribus 

 margine non reflexis, theca in pedunculo gracili elongato cylindrica 

 erecta, operculo conico-rostrato. 



Hab. Gipps* Land. (No. 78, 1855.) 



Near to D. Schimperi, Mont., but differs in its wider, acute leaves, 

 not cucullate and obtuse, and in the shorter and broader perichaetial 

 leaves. The peristome appears to have the same structure- 



19. Tortula califcim, Schw. (No. 9, 43, 127, 147,-40, 73, 1855.) 



20. T. Tasmanica, Hampe. (No. 149,-165, 1853.) 



21. T. Eornschuchiana, Schultz. (No- 33.) 



22: T. luteola. Mitten ; dioica, caule erecto ramoso, foliis patentibus 

 lanceolatis ovato-lanceolatisve obtusis nervo in mucronem flavum 

 excurrente, perichaetialibus ovato-lanceolatis sensim acuminatis, theca 

 m pedunculo aurantiaco cylindrica, operculo subulato, annulo sim- 

 plici, peristomio dentibus e basi brevissime coadunato longiusculis 

 pluries contortis. 



Hab. Yarra. (No. 132, 1855. No. 47.) 



Larger than T. unguiculata, and distinct from it in the subulate 

 points of its perichsetial leaves ; in other respects very closely allied to 

 it, and like it very variable in the width of its leaves. 



23. T. Australaaue, Hook, et Grev. (No. 35, 142.) 



24. T, serrulata. Hook, et Grev. L. 



25. T.prviceps, De Notaris. (T. Mullen, BrncL) (No. 37, 116, 1855.)
