CONTRIBUTIONS TO THE PHYTOGRAPHY OF 

 TASMANIA. 



By Baron Ferd. von Mueller, C.M.G., M.D., F.R.S. 



(IV.) 



The majority of the notes, offered now to the Royal 

 Society of Tasmania, were written more than a year ago, 

 being the result of various researches on Tasmanian plants 

 since I had the honour of submitting the third contribu- 

 tion ; but this offering was delayed, because it was my 

 wish to follow up some field-work, which I instituted in 

 Midsummer of last year, while travelling, accompanied by 

 Mr. S. B. Emmett and his son, from Circular Head to the 

 Arthur River, chiefly, Avith a view of making some special 

 comparisons between the vegetation of North-west Tas- 

 mania and that of the opposite coast of the colony of 

 Victoria. This wish of revisiting the island could not yet be 

 realised ; and as there seems to be much uncertainty when 

 effect could be given by myself to such a desire for further 

 Tasmanian phytographic explorations, I deemed it best to 

 submit my ready notes, especially as they became disin- 

 terestedly augmented by communications of plants and 

 memoranda from Mr. Robt. M. Johnston who, as a com- 

 panion of the Hon. J. R. Scott, traversed for scientific 

 purposes last autumn a large tract of alpine country, also 

 not previously examined for plants. Furthermore the 

 present contribution has been greatly enriched by notes 

 furnished by the Rev. W. W. Spicer, who, chiefly by the 

 aid of friends, obtained plants from several localities of 

 Tasmania previously but little searched, and who is likely 

 thus to advance greatly our insight into the exact geo- 

 graphic distribution of the species over the main island 

 and the adjoining islets. 



Some Algse have also been added from more recent 

 collections perseveringly formed by Mrs. Meredith, and 

 through my mediation rendered available to Dr. Agardh 

 of L\md, the great worker for a very long time on the 

 oceanic plants.
