Specimens communicated to me from " Herb. Mus. Paris ex herb. Ad. Brongniart, 

 1864, and labelled E. Leucadendron Reinwardt and E. alba Reinwardt," appear to be 

 the latter species. 



6. E. tertifica F.v.M. 



Arborea, ramulis tenuibus fceretiusculis, Eoliis alternis tenui-coriaceis breviuscule petiolatis ovato vel 

 angusto-lanceolatis antice longe acutatia tenui-venosis opacis imperforatis, vena longitudinali ad marginem 

 valde approximata, umbellis axillaribua solitariis vel terminalibus subpaniculatis, pedicellis angulatis

Leichhardt, op. cit., p. 413, says : — 



" I called this river the " Macarthur," in acknowledgment of the hberal support 

 my expedition received from Messrs. James and William Macarthur, of Camden." The 

 Macarthur River runs (it is presumed, for the whole of its course has not been explored) 

 into the south-western part of the Gulf of Carpentaria. 



In Journ. Linn. Soc. iii, 92, specimens from the Upper Macarthur River (presum- 

 ably collected either by Leichhardt or Mueller) are referred to E. tectifica. 



But as regards the second specimen quoted in the original description, viz., 

 " N. Holl. Sub-trop. Mitchell in herb. Hook." Bentham {B.Fl. iii, 243, under E. alba) 

 says that " Mitchell's specimens, referred by Black in Journ. Linn. Soc. iii, 92, to 

 E. tectifica, belong to E. dealbata, the leaves of which sometimes assume the form of 

 those of E. alba, but with a different venation." Therefore only the Macarthur River 

 specimen (the type) can be referred to E. tectifica. 



E. tectifica was so called because " the bark of the Carpentaria tree (was) persistent and rough, as 

 well on the branches as on the stem, though it is certainly pale outside and is used by the aborigines there 

 for constructing the rude roofs of their sleeping-places " .... {Eucal/yptografkia under E. alba). 



" E. alba has the leaves nearly aequilateral, the almost hemispherical calyx-lid protracted into an 

 umbonatc apex, the capsules 3--.1 celled, the valves barely semi-exserted, and the seeds wingless. The 

 identity of E. tectifica with E. alba is not yet established beyond doubt." (Mueller, Papuan Plants, i, 9.) 



Mueller evidently removed this doubt later, for in his " Second Census " he omits 

 E. tectifica, and no other inference is possible other than that he considered it a synonym 

 of E. alba.
