Following is a locality at the foot of the Blue Mountains : — 



At Higgs' Farm, on the left bank of the Nepean, about 4 miles south of the 

 confluence with the Grose opposite Yarramundi (R. H. Cambage and J.H.M.). 



Here we have a southern locality : — 



Blue Gum Gully, Thirlmere (C. F. Laseron, quoted by R. T. Baker, Proc. 

 Linn. Soc. N.S.W.,xxxi, 714). 



It is evident that more careful search will extend the range of this species, 

 and we particularly want localities connecting those already given. 



AFFINITIES. 



1. With E. polyanthemos, Schauer. 



The juvenile foliage being a character of fundamental importance, I feel I have no option in 

 separating the coast Red Box from E. polyanthemos. It seems to stand in the same relation to E. 

 polyanthemos that E. conica does to E. Baueriana, and whether it should be looked upon as a variety of 

 E. polyanthemos or a distinct species is a matter of opinion. While I propose the name E. Rudderi for it, 

 in honour of Mr. Augustus Rudder, others may be inclined to call it var. Rudderi of E. polyanthemos. 



The principal differences are indicated as follows : — 



E. Rudderi. E. polyanthemos. 



Trunk with fibrous bark somewhat like the Trunk with flaky bark (like E. tereticornis) 



ordinary Grey Box (E. hemiphloia). or nearly smooth like a Gum. 



Juvenile foliage lanceolar. Mature foliage Juvenile foliage broader, even tending to 



thinner and more uniformly lanceolar. orbicular. 



The above is a note to the original description, and is misleading to the 

 extent that I now do not think it can be viewed as other than a distinct species. 



2. With £. Baueriana, Schauer, var. conica, Maiden. 



Juvenile leaves of this variety glaucous, thicker than that of E. Rudderi, 

 broader, often triplinerved, mature leaves narrower, fruits more conoid, timber 

 brownish. 



3. With E. crebra, F.v.M. 



The anthers are different ; El. crebra is an Ironbark with red timber. The 

 juvenile foliage of E. crebra is narrower and not so prominently veined. At the 

 same time fruiting twigs of the two species are often sufficiently similar for a word 

 of caution to be necessary. 



4. With E. quadrangulata, Deane and Maiden. 



In the forest E. quadrangulata much resembles E. Rudderi, Maiden, of the North Coast, partly 

 from its growing in corresponding situations, and also because the tall straighc boles and branches of each 

 are covered with similar grey Box-bark ; but the juvenile foliage and timber afford a ready means of 

 distinction to the field botanist. (R. H. Cambage in Proc. Linn. Soc. Jf.S. W., xxxi, 438.) 



Mr. Cambage has sufficiently stated the case for the present, and I will refer 

 to the two species when I deal with E. quadrangulata.
