A numerous race of beautiful dwarf mountain plants, with flowers mostly of various shades of rose, sometimes sporting into other colours in cultivation. The finer mountain kinds would be likely to thrive only on bare stony or rocky ground, and amidst very dwarf vegetation. The bright D. neglectus would thrive in any ordinary soil. Some of the kinds in the way of our own D. caesius grow well on old walls and ruins, as do the single carnations and pinks ; indeed, it is probable that many kinds of pink would thrive on ruins and old walls better far than on the ground.
