Abstract
Theories of evolution within the monocotyledons must be based on the character states considered to be ancestral versus derived in the group. Earlier, we presented two contrasted hypotheses on the origin of the monocotyledons, one regarding as ancestral certain states that are found in particular dicotyledonous groups(Magnoliiflorae-Nymphaeiflorae), the other regarding the same states as more or less derived in the monocotyledons but ancestral in the dicotyledons (Burger 1981).
