En: Phyton : Revista Internacional de Botánica Experimental = International Journal of Experimental Botany v. 41 n. 1-2 (1981)Resumen: Around the central part of the flower surface of the traps of Dionaea muscipula, the width of the outer epidermis increases an average of 28%, and the width of the stomate openings decreases ten minutes after trap closure for prey capture during the narrowing phase. The traps, with a lower lobe area of 1,76 +- 0,59 cm2, have a water content of 85,6 +- 1,52% of the living-trap weight. This water could move into the outer epidermal cells in the central to lower middle part of the lower surface of the trap during the active period of trap closure. The thickest part of the trap (0,82 +- 0,16 mm) in the closed condition is around the lower middle portion.
