men, and this is the main difference between them. Ifthis 
be so, we may also ask in what respects the Hibiscus gran- » 
diflorus of Michaux differs. We find nothing satisfactory on 
this point, except that the leaves are tomentose on the upper 
surface, instead of being merely pubescent. 
The accompanying figure was taken from plants raised in 
the garden of the Horticultural Society, from seeds supplied 
by James Osborne, Esq., of New York. ‘They were admi- 
rably managed by Mr. Gordon, to whom we are indebted for 
the following memorandum :— 
** This splendid hardy herbaceous plant thrives best in a 
mixture of sandy loam and peat, to which should be added a 
small portion of well decomposed cow-dung. lt grows 
from three to four feet in height, and flowers in the months 
of September and October. 
* Although quite hardy, it is very impatient of wet when 
in a state of rest, and is best treated as a pot plant in the 
following way :—About the middle of March repot the plant, 
and place it in a close damp pit where there is a little heat to 
startit; and as the plant produces many young shoots, select 
five or six of the strongest, and remove all the others, as they 
are produced ; afterwards water freely, and keep the plant in 
rather a moist pit during the summer. It will then flower 
freely during the autumn, which, if planted out in the open 
border, it never does. When done flowering, withhold 
moisture first from the atmosphere of the pit, and afterwards 
gradually from the roots, until the soil in the pot becomes 
quite dry, when the pot may be stowed away in a dry cellar, 
or similar place, until the following March, when it will be 
ready for starting again.
