322 Ewart and White : 



This species is apparently nearest to llaJgduid Sohinaceji, from 

 which it differs in the following respects : — 



(1) Leaves less obtuse, smaller, thicker in texture, much 



more densely beset with white felt-like hairs, and the 

 midrib not prominent underneath. 



(2) Calyx lobes narrower, less obtuse, and less than 3 lines 



long. 



(3) Flowers mostly solitary, and terminal. 



(4) Anther lobes are less distinct from each other. 



Eucalyptus lkuoxylon, F. v. M. (Myrtaceae). 



Dr. Woolls (Proc. Linn. Soc. of N.S. Wales, vol, 1, 2nd ser., 

 1886, p. 861) first showed that under this head Mueller and 

 also Bentham wrongly included the S. Australian White Gum 

 and the Red Flowering Ironbark. The name of E. Leucoxylon 

 can be restricted to the former, as proposed, but if the name E. 

 sideroxylon is to be given to the Red Flowering Ironbark, it 

 cannot be given on A. Cunningham's authority. In the Kew 

 Index, and in Baker's Research on the Eucalypts, p. Ill, and 

 also in Benth. Flora, the reference is given as E. sideroxylon, 

 A. Cunn., in Mitch. Trop. Austr., 339 (name only). The re- 

 ference actually is, " Among the larger forest trees was a 

 Eucalyptus, allied to, but probably distinct from, the E. 

 sideroxylon, A. Cunn." This is a most curious reference on 

 which to base a species, a casual reference to a name by another 

 writer. Dr. Woolls does not give a formal description, but 

 details the differences between the two species very fully, and 

 the name can only stand on his authority as C. sideroxylon, 

 Woolls. 



Mr. Baker (I.e., p. Ill) notes as a specific distinction that the 

 rim of the capsule soon becomes detached in E. sideroxylon. 

 Tlie same applies, however, to E. LeAicoxylon, iis is well shown in 

 specimens forwarded by Mr. A. D. Hardy from Studley Park, 

 Oct., 1909, but this does not affect the validity of the two 

 species. As in many Eucalypts, the length of the style varies in 

 different flowers of E. sideroxylon even when taken from the 

 8ame tree.
