Further contributions to the history of the fossil flora of Tasmania. Part II

The second of this series of contributions to the our history of Fossil Flora refers largely to collections of plants made by the Rev J. Button, F.L.S., from Upper Mesozoic coal measures shales in 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 collections 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.,F.G.S., our Government Geologist, for more perfect specimens of three species of undescribed, or imperfectly described fossil plants occurring in the coal measures of Fingal, Seymour, and York Plains. By the more perfect examples, thus obtained, I have been enabled to add a new genus to our list (Strzeleckia) 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 possession hitherto were too imperfect to determine their specific characters satisfactorily. 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. I have in a separate table prepared a complete classified list of all the species of fossil plants known to me of Permo-carboniferous and Mesozoic Age which have been described to date, including those new forms described in this contribution. This table (embracing 75 species) is also arranged to show what I now conceive to be the probable order of succession of the principal groups and formations; and against each recorded their respective floras for the benefit of the stratagraphist and the mining expert
