mention that a young tree, bearing a profusion of lanceolate 

 leaves, very glaucous, being almost white and even silvery, and 

 gracefully pendulous, is one of the most beautiful plants we have, 

 and a fit emblem of purity. 



On Apparknt Hybridisation between E siderophloia, Bentii., 

 and E. hemiphloia, F.v.M. 



For many years certain trees partaking of the characters of 

 both the above have been known to local residents in the County 

 of Cumberland, and have received distinctive names. The Rev. 

 Dr. Woolls (Proceedings, v. 504) has drawn attention to them. 

 We have specimens selected from six different trees, which we 

 may call a, b, c, d, e and/", and will describe their characteristics. 



The anthers of a and b doubtless are like var. E. siderophloia; 

 these open in parallel slits, not in pores as do those of c, >/, e, 

 and/! 



(a) is the normal E. siderophloia, Benth. The tree grows 

 pretty plentifully throughout the Bankstown and Cabramatta 

 district, and is the only form recognised as Ironbark b} r the 

 residents. The fruit is a little shorter and broader than that 

 figured in the Eucalyptoyraphia. 



b) is the Black Box of the Bankstown and Cabramatta district. 

 Mr. J. L. Boorman describes the bark as rough (somewhat like 

 Box), but sometimes it is scaly; the colour seems to vary con- 

 siderably from black to pale brown. The timber is yellow and 

 paler than that of E. siderophloia, interlocked in grain, excep- 

 tionally heavy and is very superior for all purposes; in the neigh- 

 bourhood of Penrith it is sought after for making mauls. The 

 buds are blunter than those of E. siderophloia, the anthers are 

 similar, but the valves of the capsules are less exserted than those 

 of E. siderophloia growing in the same district. The tree grows 

 to a fair size, with long, pendulous, acuminate, glossy leaves. 



In the specimens c, d, e and f the resemblance of flowers and 

 fruit to E. hemiphloia is much greater than to E. siderophloia. 

 The anthers open in pores, the fruits are broader and less cjdin-
