168 TWO WELL-KNOWN SPECIES OF EUCALYPTUS, 



Ovary half the length of the bud, placenta attached to the top and 

 bottom of the ovary. 



Fruit sessile, conical, truncate, with a ring just below the rim, 

 3- or 4-celled, valves not exserted. 



Hah.— Monga (Braidwood, 'F. Bauerlen) ; Delegate (Bombala, 

 W. Bauerlen); Wingecarribee (IF. Woolis) ; Hill Top {J. H. 

 Maiden); Barber's Creek (H. Rumsey). 



Under E. Stuartiana, F.v.M., (B.Fl. iii. p. 244) Bentham gives 

 a variety longifolia. which Baron von Mueller states in his 

 Eucalyptogi'aphia, Dec. 4, belongs to E. punctata, " Grey 

 Gum. ' Now this latter species occurs throughout nearly the 

 whole of the coastal area of this colony, and also at the same 

 spot from which the material was obtained on which this new 

 species is founded, and as I believe I am familiar with all the known 

 varietal forms of E. punctata, I cannot admit that this species 

 is a variety of " Grey Gum." In a paper read before the Roy. 

 Soc. N.S.W. Vol. xxxi. 1897, by myself and colleague, Mr. H. G. 

 Smith, "on E. juiuctata, particularly in regard to its essential oil," 

 the systematic botany was fully treated, and I endeavoured to 

 bring this species under one of its varietal forms but could not, 

 as in so many of its physical properties it stood quite alone, and 

 so I decided to give it specific rank. 



In botanical sequence this species should probably come between 

 E. saliyyia, Sm., and E. punctata, DC, of Baron Mueller's classifi- 

 cation in his Second Systematic Census of Australian Plants, 

 p. 90, whilst it also has affinities with E. Gannii, Hk., which 

 precedes these two species, and the E. Stuartiana of Mueller in 

 his Eucalyptographia, 4th Decade Its similarity to this latter 

 species is very marked in the young and occasionally' the mature 

 leaves, and it is easy to understand how these two trees could 

 easily be confused by working on herbarium material alone. 

 There can be no doubt now that all future determinations of 

 Eucalyptus trees must be made on a personal knowledge of the 

 living trees, and a comparison of all their parts, products and 

 habits, with cognate species. In this particular instance, if I 

 had not examined the bark, wood, oil, ifec, from Baron von Mueller's
