PO:0025400 フィロム向軸側分裂組織 (Japanese, exact) phyllome adaxial rounding meristem (narrow) meristema adaxial del filoma (Spanish, exact) Laurel_Cooper plant_anatomy Contributes to the thickness of a phyllome (PO:0006001). There are two types of adaxial meristems. In phyllomes with a petiole (PO:0020038) and lamina (PO:0025060), an adaxial rounding meristem occurs later in development, is separated from the apical meristem (PO:0020144), and contributes to the thickness of the petiole and midrib. In unifacial phyllomes, the an adaxial meristem occurs earlier in development, is close to but separate from the apical meristem, and contributes to the thickness and cross-sectional shape of the entire phyllome. If annotating to a leaf, use the more specific term leaf adaxial meristem (PO:0025401).
