tightly between limestone in a hot, dry place ; 
strong loam should be added to the limestone. 
No sand or leaf-mould must be used. This 
is the only species that requires special care. 
The others grow well in any ordinary loam 
and sunny place. 
EURYBIA GUNNIANA. Purely a rock plant 
of easy culture, requiring a very dry place. 
Plant in rubble between stones, full south ; 
little or no soil need be used. The principal 
thing is to keep it as dry and as poor as 
possible. It should be well protected from 
the north and east winds. It requires knifing 
well back every year just after it has done 
flowering, so as to keep the plant compact; 
the sheets of snow-like blossoms in June 
and July are beautiful. 4. zlzczfolia requires 
the same treatment. It flowers a little later 
and is a more hardy plant, but not quite so 
free in flowers. In very hard weather a 
branch should be thrown over &. Gunnzana. 
GALAX APHYLLA (WV. America). A charming 
little bog plant; a shady position, peat, leaf- 
mould, and loam in equal parts ; top-dress in 
the autumn.
