Botanical Name. Eucalyptus, already explained, Part II, p. 34; Dalrym- 
pleana, in honour of Richard Dalrymple Hay, Chief Commissioner of Forests of 
New South Wales, whose name will ever be connected with his arduous endeavours, 
extending over a number of years, to place the working of the forests of New South 
Wales on a sound basis.

Vernacular Names. This tree does not possess an exclusive vernacular 
name. The name " Mountain Gum " is usually given to it in the mountain district 
in which it is best known e.g., Yarrangobilly, Batlow, Tumberumba, &c., but this 
is a name previously applied to E. goniocalyx in other parts of the State. Similarly, 
the name " White Gum " is shared with E. viminalis and E. rubida. It is also a " Manna 
Gum," a name it shares with E. viminalis and E. rubida.
