The relationship among the major angiosperm groups are modeled based on cladistic analyses primarily using RAPD technique. Phylogenetic trees of relationship derived from molecular data confirm dicots as the ancestral class of monocots, there seems no dicot-monocot split. Dicots form an ancestral class of magnoliids and the monocot lineage was derived from one of the basal magnoliids, since monocots share several synapomorphies dicots do not contain all the descendants of their common ancestor.
Key words: RAPD (Random amplified polymorphic DNA), rRNA (Ribosomal RNA), rbcL (Ribulose 1, 5-bisphosphate carboxylase gene).
