      Two-day and eight-day old seedlings ofAsclepias curassavica, Calotropis procera andLeptadenia pyrotechnica were studied. The basipetally differentiating epicotylar vasculature and the root-hypocotyl-cotyledonary vasculature are ontogenetically separate units. The cotyledonary node is unilacunar two-trace and the foliar nodes, unilacunar one trace. The unilacunar two trace cotyledonary nodes in advanced families like Apocyanaceae and Asclepiadaceae seem phylogenetically significant.
