New South Wales ” (January 27 th, 1892).] 
Size. —Up to 50 or 60 feet, and a trunk diameter of up to 2 feet. 
Habitat. —This tree is confined to coastal New South Wales and Queensland, 
in rich brushes. It occurs as far south as the Illawarra, and northerly into 
Queensland to Rockingham Bay, Rockhampton, and Edgecombe Bay. Particulars 
as to its southernmost limit are desirable. 
I bring this tree under notice because of its high horticultural value, which 
seems much neglected. Growing in the rich soil of its native brushes, and 
surrounded by other vegetation, it overtops its immediate neighbours, exhibiting a 
graceful palm-like trunk, surmounted by a graceful plume of large handsome 
pinnate foliage. It is a scenic plant of great beauty, and in large gardens it would 
sometimes supply a pleasing variation to palms which, if not varied as regards kinds, 
may possibly be monotonous. 
Propagation. —The fruits germinate readily.
