Merker^ found that these glands originated endogenously in the growing point between each pair of leaves. The mature glands are covered only by the epidermis, and when activity commences the uppermost cells of the gland-tip, after swelling, become detached and converted into slime (Fig. 320). Ultimately the epidermis is ruptured by the pressure of the slime, and cells are in turn rapidly transformed. Fig. 320.â gunnerae.

The Nostoc finds its way into the gland as soon as the epidermis is broken, apparently attracted there by some secretion.
