Dicotyledonous plants, commonly called dicots, are one of the two major classes -- along with monocots -- of flowering plants known as angiosperms.lurred Taxonomy. Some dicotyledonous plants are difficult to classify because they have characteristics of both monocots and dicots. This mixture of characteristics results from the shared ancestry of both classes of angiosperms.
