Fig. 31 . Growing region of stem. Model of the growing region, i.e., apical meristem region, of the stem, greatly enlarged, to show the manner of the formation and development of the leaf primordia. The model has been cut in half to show the apex of the stem, as; the ridge-like form of the last-formed, i.e., youngest, leaf primordium (l) and the overarching of the other leaf primordia over the apex.
