138 Descriptions of New, 



Port Phillip Heads, Mr. J. B. Wilson. _ 



This is so close a repetition of /. Milneana in miniature 

 that I was at first disposed to rank it as a slender variety of 

 that species. It differs in being very much more slender, the 

 branches more interlacing, the colour dirty white instead of 

 green, and in the branches being joined to each other in 

 many instances by the long, calcified bundles of tubes.
