Adventitious root formation was studied microscopically in stem cuttings of a difficult-to-root plant, the mature growth phase of Hedera helix, English ivy. Roots were found initiating at the end of 2-4 weeks in phloem ray parenchyma of internodes with and without woundwood and in callus near the basal end of cuttings; roots emerged at the end of 3-5 weeks. The fibro-bundle caps were thicker than those found in juvenile stems, but they did not hamper the development of adventitious roots.
