The suggestion that it resembles E. paniculata is unfortunate. The old steel 

 engravers did not trouble much about the venation of Eucalyptus, but the inflorescenco, 

 considering that it came from " prope oppidum Jackson," and was drawn from a 

 shrivelled specimen is, in the Australian dialect, " not too bad." A poition of the figure 

 will be found at fig. 4, Plate 161. It can be nothing else than E. corymbosa. The aitist 

 even shows the operculum hanging from the side of the calyx-tube like a hinge, which 

 is characteristic of the Blood woods and allies. 



Mueller remarks that — 



This species, as far as here noticed, is restricted to the ordinary state in which it appears through 

 the more littoral regions of New South Wales and southern Queensland. But the greatest embarrassment 

 has a~i33n in specifying the limits by which E. terminalis (E. pyrophora Benth., B.F1. iii, 257) may 

 constantly be separated ; thus Bentham already was inclined to consider both as forms only of E. corymbosa, 

 a view which the accumulation of much additional material has almost confirmed. ('Eucalyptographia," 

 under E. corymbosa.) 



It will be observed that Mueller was doubtful as to the specific limits of 

 E. corymbosa, E. terminalis, and E. pyrophora, but I think that I shall be able to make 

 the matter clear when these species are referred to. 



Then J. G. Luehma::.n, another competent authority, speaking cf E. corymbosa, 



says : — 



Including as varieties E. terminalis, E. dichromophloia, and E. pyrophora, as I find it impossible 

 o draw a clear line of demarcation ; the specimens from the dry interior and from the North- West have 

 the leaves frequently of equal colour on both sides, and the fruits are occasionally rather ovate-truncate 

 than urceolate. (J. G. Luehmann in Proc. Aust. Assoc. Adv. Science, vii, 526.) 



It will be observed that Luehmann, Mueller's assistant for over thirty years, and 

 who, besides knowing Mueller's views better than other botanists, was a close student 

 of the genus himself, thought that E. dichromophloia was (in addition to Mueller's list) 

 conspecific with E. corymbosa. 



I will return to the subject in Part XL, since it is impossible to make the 

 differences between E. corymbosa, E. terminalis, E. jyyrophora. and E. dichromophloia 

 clear without illustrations 



2. With E. dichromophloia F.v.M. 



E. dichromophloia has the fruit i con iderably mailer, al out the size of thos-i o^ E . trachyphloia and 

 E. latifolia, besides the bark seem; always different a; the spscific name iinp'.ics, from that of E. corymbosa 

 and E. terminalis, its upper thin smooth and pale stratum separating from the browrish-rd tlick layer8 

 below. ("Eucalyptographia'' under E. corymbose.) 



While I agree with Mueller in keeping E. corymbosa and E. dichromophloia 

 apart, it is necessary to point out that the fruits of the latter species may be so large as 

 to constitute a real difficulty in the comparison with E. corymbosa. The relations of 

 E. corymbosa and E. dichromophloia will be again referred to when the latter species is 

 reached in Part XL, as it is necessary to have figures.
