The genus Lodelia, though much diminished in number of 
species by the separation of new genera from it, 18 eee 
still very numerous in individuals. Of these Australia has its fair 
proportion. The present is an addition to those already ve 
and seems peculiar to North-east Australia. Dr. F. ree = 
gives Brisbane river as the locality, on the authority of Mr. Hi 
and himself. Messrs. Hugh Low and Son, of the Clapton _ oe 
sery, possess living plants reared from seeds sent by a i 
from Mount Lindsay, Moreton Bay, and these (from whic ' our

well calculated for “ bedding out” im open borders, where ue 
flowers are such a desideratum. The brightness of the colour
