 (dī′kŏt′l-ēd′n) also di·cot (dī′kŏt′)
Any of various flowering plants that are not monocotyledons, having two cotyledons in the seed and usually flower parts in multiples of four or five, leaves with reticulate venation, pollen with three pores, and the capacity for secondary growth. The dicotyledons, which include the eudicotyledons and the magnoliids, are no longer considered to form a single valid taxonomic group.
