FURTHER CONTRIBUTIONS TO THE HISTORY OF 



THE FOSSIL FLORA OF TASMANIA. 



Part II. 



By R. M. Johnston, F.L.S. 



{Read May 20th, 1895.) 



The second of this series of contributions to the history of 

 our Fossil Flora refers largely to collections of plants made 

 by the Rev J. Button, F.L.S., from Upper Mesozoic coal 

 measures shales m the neighbourhood of Dunally, which 

 collection this accomplished naturalist kindly placed at my 

 disposal It will be seen from the notes, descriptions, and 

 figures which follow that I have been enabled by these collec- 

 tions to add to the list several interesting plant forms new 

 at least to our Tasmanian Fossil Flora, 



With one or two of the forms, new to science, it has afforded 

 me great pleasure to associate the name of the discoverer 



I am indebted also to my friend, A. Montgomery, M.A. 

 -B.G.S., our Government Geologist, for more perfect specimens 

 ot three species ot undescribed, or imperfectly described 

 fossil plants occurring in the coal measures of Fingal' 

 Seymour, and York Plains. b ' 



By the more perfect examples, thus obtained, I have been 

 enabled to add a new genus to our list (Stneleekia) of 

 Mesozoic plants and also three new species. I had long been 

 on the outlook for perfect examples of these forms, which I 

 recognised many years ago ; but the specimens in my posses- 

 sion hitherto were too imperfect to determine their specific 

 characters satisfactorily. »ptuuc 



I have also added to the list one or two interesting forms 

 obtained by myself some years ago from shales of Upper 

 Mesozoic Age at Lord's Hill, New Town, and elsewhere. 

 rrf ii^ 6 m a . se P arate ta ble prepared a complete classified list 

 ot all the species of fossil plants known to me of Permo-carbo- 

 mterous and Mesozoic Age which have been described to date, 

 including those new forms described in this contribution! 

 J-nis table (embracing 75 species) is also arranged to show 

 wnati now conceive to be the probable order of succession 

 J-Uie principal groups and formations ; and against each 

 We recorded their respective floras for the benefit of the 

 Mratagraphist and the mining expert,
