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 some- 

 times assume the form of those of E. alba, but with a different venation." Therefore, 

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



AFFINITIES. 



1. With E. alba Reinw. 



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." (Mueller in " Eucalyptographia," under E. alba.) 



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

 umbomate apex, the capsules 3-4 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). 



E. alba is a smooth-barked tree. 



2. With E. platyphylla F.v.M. 



The rough, persistent bark of E. tectifica sharply separates it from E. platyphylla, 

 while the leaves appear to be longer and narrower, and the buds more acute. 



3. With E. pastoralis S. Moore. 



This is also a smooth-barked species, while E. tectifica appears to belong to the 

 Boxes. The leaves and buds of the former are also distinct from those of the latter.
