Re: Can a plant be both monocot and dicot?

The best answer is no because each flowering plant species can be classified as 
either a monocot or a dicot, not both. 

Monocots and dicots are generally distinguished from each other by several 
characteristics, including cotyledon number, root system type, leaf venation, 
numbers of flower parts, and vascular bundle arrangement in the stem. However, 
sometimes a particular monocot species may have some characteristics like a 
dicot and a particular dicot species may have some characteristics like a 
monocot. For example, one exception to the rule that dicots have two cotyledons 
and monocots have one cotyledon is the dicot water lily (genus Nymphaea) which 
has what appears to be one cotyledon with two lobes, but which is usually 
considered to be two cotyledons that have fused. Because water lily is a dicot 
but has what appears to be one cotyledon, it could possibly be considered a 
dicot with a monocot, which means "one cotyledon".
