Self-fertilization has been guarded
against by precarious means, but the safest of all devices -
separation of the sexes on distinct plants. These are absolutely
dependent, of course, on insect messengers - not visitors merely.
Bees, which always show less inclination to dally from one
species of flower to another than any other guests, and more
intelligent directness of purpose when out for business are the
groundsel-bush's truest benefactors. This is the only shrub among
the multitudinous composite clan that most of us are ever likely
to see.
