Stomata are not present, at least in a perfect form, in any submerged 240. As appears from the following figures, the first stage in the devel- opment of an ordinary stoma is the separation of a part of an epider- mal cell by means of a vertical partition, thus forming the mother-cell of the stoma. This next divides by a verti- cal plane •which soon exhibits a narrow chink, their common wall may.
