HYDROLEA SP1NOSA. 
I 
We are anxious to lose no opportunity of impressing upon culturists the advantag 
of ascertaining what exotics we possess that will do in the climate of Britain. Ther 
are many among those which are ever regarded as stove plants that would compet 1 
with the most hardy in the summer season in that respect, if they had an opportunit 
of doing so. At the least, the fact of their doing well in the stove, and the poss: 
bility that they may not succeed out of it, should be no obstacle to prevent cxper 
ments having this object in view being tried. 
Hydrolea spinosa increases with great facility by cuttings, and also seeds abund 
antly, hut how far the latter are useful in producing plants, we have not had ai 
opportunity of ascertaining; their formation occurs to such an extent under som 
circumstances as to require the repeated removal of the vessels which contain them 
to enable the plants to continue vigorous. Our drawing was taken in summer, a 
Messrs. Bollisson’s. 
The generic name is one of Linnaeus’ founding; and is derived from Jiudorl 
water, and elaia, oil, alluding to the situation and nature of the plant.
