Abstract
The protoplasmic continuity in the meristoderm and outer cortex of the blades of Egregia menziesii and Fucus evanescens is demonstrated by electron micros copy. Groups of small pores of the order of 37.5 mμ in diameter perforate the walls in these regions. Traversing the pores are protoplasmic strands connecting the adjacent protoplasts. It is concluded that these pores are plasmodesmata which occur in primary pit fields. Endoplasmic reticulum is not found within the plasmodesma.
