The parsleys are a family that we should all learn to know, if for no other reason than that the root and seeds of many of them are extremely poisonous. This is true of the water-hemlock illustrated in Plate VI. Again, we cannot avoid all of them on this account, as among them they number the vegetables, celery, carrots, parsnips and parsley. They are readily recognised as a genus by their umbels and umbellets of minute flowers, compound leaves, and generally hollow stems. In size and colour they are very variable.
A powerful microscope and a lifetime of patience is necessary to study them in the detail of their individual parts, and many of the species can only then be recognised by the difference in their fruit; but they can be broadly known according to locality. Insects are necessary to them, as self-fertilization is prevented by the stigma developing some time before the stamens.
