摘要: A study of the fine structure minor veins mature leaves 975 species and 242 families Angiosperms shows that transfer cells are widespread amongst herbaceous Dicotyledons, much rarer in woody virtually absent from Monocotyledons. The evolutionary significance distribution within orders, groupings is discussed.
