Ontogeny and Marginal Growth in the Leaf of Eubrachion ambiguum

Marginal growth in the leaf of Eubrachion ambiguum, a viscaceoushemiparasite, has been investigated. This growth is accomplishedby the marginal meristem comprising the marginal initials aloneas has been described earlier by Hara (1957) in Daphne odora.To the best of the author's knowledge the present communicationis the second report of such a type of marginal growth in thedicotyledons. Phylogenetically, at least in Eubrachion ambiguum, it probablyrepresents a reduced rather than a primitive feature.
