H.-VBITAT. 



It is perhaps qnite safe to say that this species is facile princcps over its 

 congeners in extent of geographical distribution, for it is found in all the States, 

 but nearly cdways away from the coast. 



I. HISTORICAL. 



This species' name was founded by Robert Brown in 1825, and his selection 

 was happily chosen, as the leaves partake of a glaucous character, more pronounced 

 than in any other species of Callitris. It is a feature that differentiates it also in 

 herbarium material from all its congeners, and it retains it wherever the trees 

 grow, either in the eastern, central, or western parts of the continent, irrespective 

 of en\'ironment. The claims of this species to specific rank were apparent to us 

 long before seeing Brown's original specimens, and had Bentham seen Brown's 

 species, — C. rohusta, C. glauca, C. tuberculata, and C. verrucosa, in the field, he 

 would not, we tliink, have synonymised them as he has done in the "Flora z\us- 

 traliensis," \o\. \T, j). 237, under the name Frenela rohusta. Cunningham also 

 regarded them as distinct, as shown by his specimens and MS. in the British 

 Museum. Each of these species is readily characterised by the fruits alone, and 

 even the two species C. verrucosa and C. rohusta, with warted cones, cannot well 

 be confounded. 



A paper on this species was read by us before the Royal Society, N.S.W., 

 August, 1908, Vol. XLII, portions of which are embodied here.
