ON THE GENERA KENNEDY A AND DILLWYNIA.

quantity of moisture will be required, in fact the atmosphere of 
the house must be kept constantly supplied with vapour, not to 
the extent certainly requisite for inter-tropical plants, but to an 
amount easily appreciable : to the practical man we can readily 
explain the kind of atmosphere and its changes, most congenial 
to the full development of the several beauties of these plants, 
by stating that an early vinery is exactly the place in which to 
grow Kennedyas. When the plants require shifting from the 
pots last mentioned, they should be turned at once into those it 
is intended to bloom them in ; and it should be remembered that 
the larger these pots (so that the removal is effected early 
enough) the larger will be the plants, continuing to treat them 
as directed until they are about to expand their flowers, when 
a somewhat drier atmosphere will be better for them : this change 
must be brought about gradually, but certainly so that by the time 
the plants are in perfection, they may be standing in a cool and 
perfectly dry air, which will preserve their beauty for a long period. 
The management of Dillwynia differs considerably from that 
just described, as they possess a far more robust character, and 
may be assimilated in treatment to heaths or the majority of 
Australian plants: they delight in sandy heath-soil interspersed 
with lumps of charcoal, broken potsherds, small stones, roots, 
and other matters "conducive to the maintenance of an open 
porous soil, through which water and air may freely percolate. 
If the above conditions are fully observed, there is perhaps no 
plant which may be grown to greater advantage under the 
treatment usually denominated the <( large shift system. 
Placed at once from a 60 into a 16-sized pot, and allowed an 
abundance of air from the earliest favourable opportunity 
until the decline of autumn, it is surprising the advance a 
plant of this nature will make: a luxuriant vigour is imparted 
quite unknown to those grown in small pots, even though they 
are shifted with the greatest care through all the intermediate 
sizes. 
A point of the most immediate consequence to the pro¬ 
duction of handsome, well-filled specimens is the constant re¬ 
moval of the terminal buds of the growing shoots ; it should be 
done as often as the new stems have shot forth two or three 
joints. This stopping, as it is called by gardeners, throws ad¬ 
ditional strength into the parts already formed, and induces 
them to protrude other shoots from the lateial buds situate in
