Scanning electron microscope image of cross-section through a Psidium guajava stem. The image shows the thin outer epidermal layer with a thick layer of cortex beneath. The vascular area consists of a secondary phloem and primary xylem, with vascular cambium in between. The central pith has some mucilage present.This image is part of a group on botanical stems (CIL:40378-40395).
