The character of CaLoris was formed, but not pub- 
lished, by Mr. Brown about fifteen years ago, from C. 
denter, a species first observed by himself in New Holland, 
where it is not uncommon in the neighbourhood of Port 
Jackson. The present has been since found, during an ex- 
pedition into the interior of the above country, growing on 
the banks of the river Lachlan, in 1817 by Mr. Állan Cun- 
ningham, who is commended by Mr. Brown, as “ an inde- 
fatigable collector and acute observer." It was introduced 
in 1819 at the Physic Garden, Chelsea. 
The generic name has been derived from the two mem- 
branous earshaped palew of the seedcrown, which are con- 
stant in number and form in the only two certain species yet
