196 TYPES OF BRITISH PLANTS 
know, depends almost wholly on self-fertilisation, but the 
campions draw moths and bees to them by their bold and 
handsome flowers. I have not space to do more than 
allude to some of the commonest. The pink campion 
is generally to be found setting off the bluebell’s colour 
on shady banks in May, though, being of hardy nature, 
it will often wander forth to the roadsides. In drier 
ground, and a month or two later, lifting its purple 
top amongst the corn, one may find the Corn Cockle. 
Whether it be due to more careful weeding of the crops 
I do not know, but it is certainly my own experience that 
this beautiful flower has become much rarer in the last 
ten years, and I count it now amongst the successes 
of an afternoon. 
To find the Ragged Robin, which gets its name from 
the deep-cut segments of its red petals, we must reverse 
the process, and go off to marshy ground. Once found, 
there is no chance of its being mistaken for any other 
English plant, for its petals at the first glance look 
as if they had been snipped about with scissors, and 
remind one of an early yellow crocus which has had the 
misfortune to annoy the dignity of a sparrow, and has 
been pecked to pieces as a punishment. The Bladder 
Campion is known at once by its heads of white flowers, 
and by the inflated calyx from which it gets its English 
name. There is a curious copartnership of this flower 
-with one of the Noctue moths. The moth does the 
work of fertilising it, and in return the caterpillar 
employs the bladder-like calyx as its daily agin ne 
and the mutual advantage is thus secured. 
Both Campions and Chickweeds abide by the ene 
number five for sepals and petals, but in the former the 
sepals combine into a single tube at the base, only
