Comment
Many species have juvenile leaves at the base of the stem, adult leaves at the apex, and transition leaves in between. In maize, juvenile leaves are at the tip of the stalk (stem), which differentiates first, with adult leaves at the base, while other grasses may have other arrangements. The first juvenile leaves in Poaceae are the embryonic leaves found in the grass kernel (caryopsis).
