312 BOTANICAL NOTES FROM THE TECHNOLOGICAL MUSEUM, 



Eucalyptus punctata, DC. 



This species extends from Rylstone to Capertee. Not in Mr. 

 Hamilton's list. 



Eucalyptus saligna, Sm., var. 



The Grey Gum of the north coast districts. This gum yields 

 a timber of economic importance, as it bears the highest local 

 reputation for durability, and it is one of the best known iron- 

 bark substitutes. It has also certain affinities to E. vhninalis. 

 It became a matter of importance a few months ago to determine 

 its botanical position with precision, and we show it to be a 

 variety of Eucalyptus saligna (usually known as Blue or Flooded 

 Gum in New South Wales), and we indicate its relation to the 

 typical species and to E. vhninalis, Labill. 



Grey Gum. 



Flower-huds : Generally resembling E. saligna, but operculum 

 less drawn out to a beak, the calyx and operculum being far more 

 globular and also smaller, operculum dome-shaped. 



Flowers: Anthers most like those of E. saligna. Blossoms 

 in January and February. Upper Gloucester (Rudder). 



Fruits : Strongly resemble in outward appearance those of a 

 small-fraited form of a Manna Gum, such as is found at Bombala 

 and other places in southern New South Wales. Fruits in tens 

 (usually). Rim broader, and its edge sharper. Fruits usually 

 rather smaller and more conical or angular in shape. Common 

 pedicel very flat and about an inch long. Invariably pedicellate 

 as far as seen. 



Leaves: Resemble E. saligna as regards consistence and vena- 

 tion. They are very different from those of E. viminalis. 



Bark: Invariably deciduous to the roots. Grey, with a loose 

 mealy surface. 



Timber : A most lasting timber. " I have seen a post, 40 years 

 in the ground, which shows no sign of decay " (Rudder). Is red, 

 and might easily be mistaken for ironbark.
