| Posteriorly, the mesial lamina of the splenial is firmly sutured onto the anterior end of the prearticular. |
| The cells were surrounded by a basal lamina and joined by primitive junctions. |
| To estimate the relative surface area of basal lamina and apertures, we used a line intercept technique with cycloids. |
| The width of the fenestrated layer between the basement membrane and the cellular cortex of the lamina monopolar cells is reduced. |
| The leaf petiole incurvates, the lamina swells, the central bud loses its structure and the central inflorescence does not form. |
| For each plant, the coordinates along the axis of the stem and the midrib of each lamina were recorded. |
