with in the vicinity of the Bulwer Pilot Station (Moreton 
Island), and that are more or less charactersitic of the 
ericetal vegetation of the coastal districts in the latitude of 
Brisbane, the country traversed being of a dry sandy nature 
(sea-board, flats, amd hills of low elevation) although 
comprising also extensive swamps tending to become dry 
in summer. 
Trailing over the sand-hills facing Moreton Bay grow 
that peculiar grass Spinifex hirsutus, remarkable for having 
the female spikelets in dense globular heads, and the male 
ones in spikes forming usually clusters of two or three ;

ajquilaterale. Here and there amongst them were small 
colonies of Stackhousia monogyna, and the blue-flowered 
lobelia. On their summits commonly grew Acacia longi- 
folia, var. Sophorae, and a pungent-leaved epacrid with 
small drupaceous fruit. Whilst behind them and between
