Fern rhizome, light micrograph. Transverse section through the center of a rhizome from the Killarney fern (Trichomanes speciosum). Thick-walled sclerenchyma cells (black-red) surround the central vascular cylinder (stele). From the outside of the stele inwards are four thin layers: the endodermis (red), the pericycle, and two layers of phloem. In the centre are the large thick-walled cells of the xylem. Magnification: x100 when printed at 10 centimetres wide.
