regard to the placing of this and that intermediate specimen in one species or the 

 other. This is inconvenient, hut the convenience of taxonomists has to give way to 

 the grand law of variation. 



I look upon E. Wilkinsoniana, B. T. Baker, and E.jiigra, B. T. Baker, as 

 heing inseparahle from E. eujenioides on the one hand and from E. Muelleriana en 

 the other,* and I have made careful investigations in the forest. 



E. Wilkiiisoniana, E. T. Baker, Proc. Linn. Soc. N.S.W., 'xxv, 678 (1900). 

 Syn. according to Mr. Baker. E. Jicemastoma,\ Sm. var. (Mueller in Eucalyptographia 

 Dec. 2) ; E. l&vopinea, var. minor, Baker. 



The affinity of E. Wilkiiisoniana with E. Muelleriana is an inference already 

 made hy Mr. Baker, partly on oil determination, but made by me on morphological 

 grounds. Mr. Baker's original view was that this tree is a small-fruited form of 

 E. Muelleriana (his Icevopinea) and I think that that view has much to support it. 

 It, however, ignores the obvious relation to E. eugenioides. 



The type of E. Wilkinsoniana came from Marulan, also Barber's Creek 

 (H. J. Eumsey). Specimens were sent to me also from the Glenrock paddocks, 

 Barber's Creek, by H. J. Eumsey. Type specimens also from Sutton Forest 

 (E. T. Baker). All these localities are very familiar to me, and the tree was 

 collected by me long before it was described. Specimens from Burragorang 

 (E. T. Cambage) and many other localities also match the type. 



The fruits varv a good deal. See the remarkable differences of the forms of 

 two heads of fruits from the same branch at Barber's Creek (H. J. Eumsey, the 

 original collector of the type specimens). See fig. 17, pi. 38. 



Mr. Baker's statement in his description of E. Wilkinsoniana that E. 

 Icevopinea never has a red rim appears to be founded on a misapprehension. 



An extreme form of the fruits (from Sutton Forest) is that shown in the 

 figure of E. Wilkiiisoniana (PL 38, fig. 18). I have precisely the same form from 

 1 mile south-west of Parramatta, Wianamatta Shale formation (E. H. Cambage). 

 Sometimes {e.g., same place and collector) the fruits are more constricted at the 

 orifice, showing transit to E. pilularis. This shape of fruit is common enough in 

 typical Muelleriana, whose fruits are, however, larger. Following is the same form. 



E. pilularis, Sm., Gladesville, Sydney (H. Beane, May, 1S86 ; J. L. Boorman, 

 Dec, 1898) normal apparently in every other respect except that the size and 

 shape of the fruits very closely approximate that of E. Wilkinsoniana figured at 

 pi. 38, fig. 18. 



The fruits of E. Icevopinea, E. T. Baker, from Gulf Eoad, Eylstone 

 (B. T. Baker) display such variation in size and shape as to have caused differences 

 of views as to the species. For example, in Proc. Linn. Soc. N.S.W., 1896, 803, 



9 See note in Proc. Linn. Soc. N.S. W., 1905, p. 509. 



tThe statement that E. hamastoma, var. is a synonym of E. Wilkinsoniana, is founded on a misapprehension. 

 See Proc. Linn. Soc, N.S. W. 1904, p. 700. The original specimen is E. Sieberiana, F.v.M.
