S ummary Particles in the plasmalemma‐cell wall area are reported in fixed and sectioned material of differentiating vascular cells of Pinus strobus L. The particles, from 13 nm to 16 nm in diameter, arise from the superficial layer of cytoplasm and reach the plasmalemma‐cell wall area apparently by a‘membrane flow.’Frequently the particles are in close spatial association with microtubules at the plasmalemma‐cell wall area. The particles observed here are thought identical with those observed on the outer surface of plasmalemma by the freeze‐etching method.
