In this country our first knowledge of this tree is derived from 
young plants kindly sent to the Royal Gardens in the autumn 
of 1851 by the Horticultural Society of London, and his Excel- 
lency Sir William Denison, Governor of Van Diemen’s Land. 
Capt. Erskine, R.N., of H.M.S. Havannah, had recently visited 
New Caledonia and some of the adjacent islands, and had invited 
Mr. Moore, of the Botanic Garden, Sydney, to accompany 
him ; and to Mr. Moore’s energy and kindness we are indebted 
for the re-discovery of this tree and for the possession of 
MARCH Ist, 1852.
