growths. In autumn, use a top-dressing composed 
almost altogether of grit with the fine sifted out, so 
that any moisture may be absorbed which would 
otherwise rest on or near the plant during the damp 
season, and especially in the months of November 
and December, when the risk of injury from this 
cause is greatest. In spring a sharp look-out must 
be kept for snails, as they are particularly fond of this 
plant. 
Dianthus neglectus (S.W. Europe). 
Plant this species in a well-drained place on the 
flat, facing full south, in equal parts of grit or lime- 
stone and of loam, but without any sand. In early 
spring, and again after flowering, top-dress carefully. 
Immediately after flowering, the flower-stems should 
either be pulled clean out or else be cut close off, as 
by doing this ripening for the next year’s flower is 
promoted. 
Dianthus Seguieri (S. and E. Europe, and Asia). 
This species is valuable for its late-flowering 
qualities. Treat like Dianthus cinnabarinus, with 
the exception that this species may be partially cut 
back in spring. 
Diapensia lapponica (Northern Regions). 
Plant in partial shade, in a well-drained place 
on the flat, facing south-west, in fibrous loam, leaf- 
mould, and sand in equal proportions. In spring 
and autumn a top-dressing of the same constituents, 
worked among the individual twigs, is most essential. 
The autumn top-dressing should have a large
