E. OVALIFOLIA, R. T. Baker, var. lanceolata, R. T. Baker & H. 

 G. Smith. " Red Box," " Slaty Gum." 



This tree very probably owes its differentiation to environment, 

 for I have onl}^ found it in rich, moist soil. It has a smooth bark, 

 lanceolate leaves (broader than E. Dmvso7ii), and an excellent 

 straight-grained, comparatively soft, red timber; in other respects 

 it resembles the type. At Lue and along the banks of the 

 streams that flow into the Cudgegong on its right bank from 

 Rylstone to Galgong, it is sometimes known as " Slat}'- Gum " 

 (J. Dawson), but it is not the "Slaty Gum" of Bjdong upon 

 which E. Datu^oni was founded. 



Remarks on the above three Eucalypts. 



These were originally placed by me as varieties of E. polyan- 

 thema, Schauer, but during the last five years much in the way of 

 new data has been collected concerning them, so that I have been 

 led somewhat to alter my first classification, and I now regard them 

 as quite distinct from that species and have so recorded them in 

 these Proceedings. 



E. ijolyanthema, Sch., has recently (Proc. Linn. Soc. N S. W. 

 1902, p 527) formed the subject of a paper by Mr. J. H. Maiden, 

 who reproduces Schauer's original description from Walpers' 

 ' Repertorium,' and also gives a figure drawn from the type 

 specimen. 



This description and figure refer to a tree that in no way can 

 be made to include any of the above trees, although Mr. Maiden 

 synonymises them with it (Schauer's E. poJya7itheinos). I have 

 in my possession botanical material identical with those of 

 Schauer's, in fact might be thought to be the type figured, and 

 these are from a tree quite distinct from any of the above three. 

 Schauer states of his tree, " Arborea glauco-virens; foil, coriaceis 

 ovatis subito in petiolum contractis obtusis apiculatis, margine 

 crasso subrevoluto cinctis impunctatis, utrinq. opacis." 



Such features are not to be found in either E. Daiosoni., E. 

 ovalifolia, or E. ovalifolia var. lanceolata, and one has only to 

 know these trees in the field and to compare their herbarium
