2. Callitris tubcrculata. 



R.Br., Mirb. in Mem. Mus., Par. xiii, 74. 



Habitat. 

 Middle Island, York Island Bay. 



I. HISTORICAL. 



This little-known Pine, placed by Bentham in the " Flora x\ustraliensis/' 

 Vol. VI, 237, as a synonym of C. rohiista, is a species of Robert Brown, and 

 probably collected by him on the same trip when he collected the latter Callitris. It 

 was this collecting by Robert Brown of his own species that led us to doubt 

 whether this synonymising by Bentham was not open to question. 



We have now seen Robert Brown's original specimens of C. tuherculata 

 at the British Museum, and find that it possesses characters that warrant, we 

 think, its being placed in specific rank. 



. II. SYSTEMATIC. 



The decurrent leaves have a glaucousness similar to C. glauca, as well as 

 terete branchlets formed by these decurrent leaves, but the cones resemble some- 

 what those of C. rohusta, except in size, being smaller and more depressed than 

 those of the true C. robusta of the same author. 



No material was available for detailed investigations.
