Specimen labelled " from Tasmania," but the fruits are immature. 



Melbourne, — 



A specimen labelled " 03'ster Ba}' Pine, Tasmania," is named C . rhomboidea 

 by }*lueller and Parlatore; the fiaiits are too small for correct determi- 

 nation, but the branclilets and locahties leave httle doubt of its 

 S3^stematic position. 



II. SYSTEMATIC. 



This is a smaU, medium-sized tree, occasionally 40 feet high and over, attaining 

 its largest size in fairly flat situations, and near water, as at Glen Regis, Redstone. 

 Branches spreading, horizontal or di'ooping, rarel}- if ever fastigiate. Branchlets 

 with the decurrent leaves stouter than in C. rhomboidea, and almost matching 

 those of C. calcarata. ]ilale amenta small, terminal, almost globular, of a lighter 

 colour than the leaves. Female amenta in panicles at the base of the branchlets. 



Emit cones densely clustered on short, very stout, much-thickened branches, 

 in this feature resembling C. robiista, R.Br., over h inch diameter, globular, valves 

 six, alternately smaller, the larger ones thick and dilated upwards into a wedge- 

 shaped apex. 



Remarks. 



One great distincti^"e dift'erence between this species and C. rhomboidea 

 will be found in its field appearance, for while C. rhomboidea is quite fastigiate in 

 its growth, C. Tasmanica has distinctly spreading, low, horizontal branches, 

 which occasionalh" di'oop, whilst thev are never fastigiate, and this featxnre 

 characterises the tree both in Xew South Wales and Tasmania. 



The glaucous feature of the leaves and the almost sessile clustered fruits 

 with tlieu" thickened valves also differentiate the species from C. rhomboidea. 

 The ver^" slender branchlets with the decurrent leaves of C. rhomboidea is also a 

 distinguishing character from C . Tasmanica. 



It is this comparative constanc\" of characteristics as well as that of the 

 chemical constituents that prompted us more especiallv to gi\"e it specific rank. 

 Very probabh* the locahty — Xew England (Stuart) — given b\- Bentham, loc. cif., 

 for C. rhomboidea refers to this species.
