The prominently tuberculated fruits of C. robiista at first led us into an 

 error, for we thought that C. titbcrcidata would prove to be that species, but after 

 seeing Brown's original specimens of the species from ^Middle Island, York Bay, 

 we were compelled to alter our opinion and separate the two [tndc note under 

 f . tiihcrculata, R. Br.) 



The trees cultixated in the Hobart Botanic Gardens and labelled C . vohusta 

 agree in every particular with A. Cunningham's specimen. The branchlets and 

 leaves never have the bluish-green, or "bloom" characteristics of those of 

 C. glaiica, R. Br., and of the fruits of C. propinqua, R. Br. The fruits are 

 differently shaped and larger than either those of C. tuberculata, R. Br. or 

 C. verrucosa, R. Br. As the result of these investigations, R. Brown's species 

 C . robiista here stands as distinct from those with which it has been synonymised. 



^Herbaria Material Examined. 



A special visit was made to Europe by one of us, and the heads of the 

 prmcipal institutions kindly placed at our disposal for examination all the Callitris 

 in their keeping, and referred to under each species. 

 Kew, — 



A. Cunningham's specimens from Rottnest Island, 1822. Drummond's 

 specimen from Swan River, 1839. Oldfield's specimen from Garden 

 Island. 



British Museum, — 



A. Cunningham's specimen, ditto, I.e. supra, Paris. Specimen from Western 



Australia, labelled by Miquel, C. Preissii. 

 Preiss' specimen from Cygnet River district, 1843, labelled, C. Suissii. 

 Cambridge University, — 



A. Cunningham's specimens ditto. I.e. supra. 

 Melbourne, — 



West Australian specimens named by Dr. Parlatore. Specimens from Bald 

 Island named C. verrucosa by F.v.lM. 



Sydney, — 



The fresh material collected and forwarded to us for in\-estigation by 

 Dr. Alex. Morrison, Botanist, Department of Agriculture, Western 

 Australia, in no wa\' dilicrs from the above original specimens, and so 

 removes all doubt hum A. Cunningham's and I\(il)crt Brown's species. 

 It also establishes the fact that after nearly a iuiiidred years the species 

 has produced httle or no variation.

' It was originally intended to use the word " types " in preference to " herbaria." lnU as soiiiu botanists 



^«nnection object to types as things fre |ucntly imaginary -a type being an aggregation of individuals — 



the latter word is here preferred, tt was only from the examination of a very large quantity of specimens that the 

 original opccies has been traced.
