ON A NEW SPECIES OF EUCALYPTUS FROM 

 NORTHERN NEW SOUTH WALES. 



By J. H. Maiden, Government Botanist and Director 

 Botanic Gardens, Sydney. 



Eucalyptus Dunnii, sp.nov. 



A large White Gum,"^ much resembling the Blue Gum {E. 

 saligna) when groNving (W. Dunn), therefore an erect grower. 

 My specimens were taken from a tree 3 feet in diameter and 70 

 feet high (measured felled). 



Bark. — Rough, flaky or more or less corky at the butt and 

 for a varying distance up the stem; thenceforward the bark hangs 

 in ribbons. " The rough bark or ribbons follow the tree up to 

 the topmost branches, and the tree always carries more of it than 

 does E. saligiia " (W. Dunn). 



Timber. — White throughout, from the sap to the heart, some- 

 what coarse-grained and fissile. Apparently a tough wood. 

 Stress is laid on the quality of this timber, as the name White 

 Gum usually indicates timber of poor quality. ]Mr. Dunn 

 writes: "I prefer this timber to that of our local Blue Gum 

 {E. saligna), the White Gum being not so free, i.e., not so liable 

 to split. It is the best White Gum I have ever seen, being very 

 free from gum veins." On asking for verification of the above 

 high estimate of the timber, Mr. Dunn wrote under date 4th 

 June: "Yesterday I measured another 14,000 super, feet of it. 

 I may say without hesitation that it is very durable, and superior 



* "Recently I measured 15 of these trees, felled for sawmill timber, con- 

 taining 28,523 super, feet; this, at the small royalty of 6d. per 100 super. 

 feet, amounted to £7 2s. 7d." (W. Dunn, 30-iv.-05).
