The film demonstrates a typical example of leaf development in ferns by speed-up film technique. The tip of the leaf primordium is growing in a spiral thus protecting the apical row of initial cells. Simultaneously a leaf unrolling proceeds in acropetal direction and also a broadening of the lamina. The longitudinal leaf lengthening can be accompanied by circadian up- and downward movements.
