This paper describes the special anatomical structure under the periderm and the reticulate distribution of the resin ducts near the periderm of the roots of Umbelliferous plants. Tangentially elongated parenchyma tissue is present under the periderm in the cross section of the roots of BuPleurum falcatum L. Although this tissue has been considered to be collenchyma or collenchyma-like tissue, according to the present microscopical observation of the radicle, it was confirmed that so-called collenchyma-like tissue is originated from pericycle under the endodermis, and that the resin ducts in the above-mentioned tissue of the roots of Umbelliferous plants including Bupleurum sp. are reticulately distributed in a single layer under the periderm. Such distribution of the resin ducts is one of the most characteristic features of the roots of Umbelliferous plants.
