718 FLORA OF AUSTRALIA, V., 



Hab. — Killerberrin (Dr. A. Morrison); South West Australia 

 (F. S. Roe); Murchisou River, W.A. (Oldfield). 



A specimen of this species was sent to me some time ago by 

 Dr. A. Morrison, then Government Botanist of Western Aus- 

 tralia, who stated that it was collected by Mr. F. H. Vachell at 

 Killerberrin in July, 1903. On comparing it with known species 

 of Gallitris, it was apparent that it was undescribed, but a trip 

 to Europe in 1904 barred my publishing a description. When 

 visiting Kew Herbarium in that year I found that similar 

 material had been collected in South West Australia by F. S. 

 Roe; and in looking over the Melbourne Herbarium upon my 

 return, I found that Oldfield had also collected specimens of this 

 Conifer on the Murchison River, Western Australia. 



The exceedingly short internodes differentiate it from any 

 described species of Callitris; whilst in the terete, glaucous 

 branchlets it approaches more closely G. robusta R.Br., and C. 

 gracilis R. T. Baker, but differs from the first of these in the 

 absence of tubercles on the cones, which latter are also smaller 

 than those of 0. gracilis, from which species it differs also in its 

 erect glaucous branchlets. From C. rhomboid ea R.Br., it differs 

 altogether in the shape of the fruit cones, and of course itcannot 

 be placed in the series with angular branchlets. The specimen 

 in the Melbourne Herbarium is labelled C verrucosa var. by 

 Baron von. Mueller, but there are no features showing a grada- 

 tion to that species. 



In the ' Flora Australiensis ' there appears to be no reference 

 to these particular specimens. 



The Kew Herbarium specimen is labelled " Inter. S. W. 

 Australia, F. S. Roe, Esq." 



G. robusta J.D.H., Hookerian Herb., is identical with that at 

 Melbourne collected by Oldfield. 



The systematic description is based on the above-mentioned 

 specimens and other notes. 



It has cones which are similar to those of G. Drummondii, 

 whilst the branchlets much resemble those of C. robusta R.Br.
