both surfaces, not shining; lateral veins spreading, but not 

 prominent, and almost quite hidden; intramarginal vein close 

 to the edge. Buds on slender pedicels from 4-6 lines long. 

 Flowers numerous, mostly in a terminal panicle. Calyx small, 

 pyriform. Operculum hemispherical or conical, sometimes shortly 

 acuminate. Ovary flat-topped. Anthers all fertile, cells opening 

 by terminal pores. 



Fruit variable in shape, sometimes cylindrical, with the thin 

 rim incurved, whilst at other times pilular in form with a con- 

 striction below the rim, 2-3 lines long as well as broad. 



Hab. — Dubbo to the Darling River ("Gum"; W. Bauerlen); 

 Nymagee, Condobolin ("Coolabah "); Mt. Hope (-'Yellow Jacket" 

 and " Gum "); Cobar (" Coolabah Gum "); Drysdale ("Coolabah"); 

 Bodabah, 30 miles E. of Nymagee, one of the most easterly 

 localities for this species. For these localities I am indebted to 

 Mr. R. H. Cambage, who also informs me that the difference 

 between "Yellow Jacket" and "Gum " is, that when rough bark 

 goes far up the tree and gives it a yellowish appearance it is called 

 " Yellow Jacket." 



Timber. —Timber very hard and red in colour, and very inter- 

 locked, in fact so much so that it is stated to be almost impossible 

 to split; and though having a good repute for durability, it is 

 very little used owing to the difliculty in splitting. It should be 

 a good timber for railway sleepers. At Eremeran Station, 30 

 miles south of Nymagee, and at Double Peak, Mount Hope, the 

 timber is used for making charcoal (R. H. Cambage). 



Oil. — Oil from leaves collected at Nyngan, New South Wales, 

 December 7th. 1899: — The crude oil is brownish-orange in colour, 

 phellandrene is not present, and no eudesmol was detected at this 

 time. The oil contains a large quantity of dextropinene proved 

 by its characteristic reactions. Between 165° and 170° C.,* 

 40 per cent, distilled, while below 185° C. only 84 per cent, had 

 distilled. The oil does not meet the requirements we recommend 

 to be demanded for a good Eucalyptus oil.
