The anatomy of endogenous bud and lateral root formation was studied in Convolvulus arvensis roots cultured in vitro. Although early stages in the initiation of buds and roots were found to be identical, continued development of primordia into roots or buds was accompanied by differences in participating primary root tissues, in rates of development, and in orientation of cell divisions. Evidence for the existence of a primordium capable of developing into either a bud or root is discussed with reference to Convolvulus roots and other plant parts shown to have similar morphogenetic potentials.
