Laticifers in stamens of Papaver somniferum L.

Articulated anastomosing laticifers were identified at both light and electron microscopic levels in the stamens of Papaver somniferum L. They were observed associated with the phloem forming a continuous system from the filament into the anther of the stamen. Laticifers, which were comparable in structure to laticifers found elsewhere in the plant, possessed numerous vesicles of different sizes within the protoplast.
