The microstructure of underground stems of Sinopodophyllum hexandrum and the distribution of endophytic fungi were studied by permanent sectioning and microscope observation.The secondary structure of the underground stems consisted of periderm and cylinders,and the periderm was composed of cork,cork cambium,and phelloderm.The parenchymas cells of secondary phloem had abundant inclusions.The secondary xylem consisted of vessels,xylary radials and parenchyma cells.Some segments of hypha were in colonies in cork and secondary phloem.Endophytic fungi existed in the local cells of cork and secondary phloem in the underground stems.
