"Dicolytedon" appears to be a misspelling or confusion with the term "dicotyledon," which refers to a group of flowering plants (angiosperms) that have two embryonic leaves, or cotyledons. Dicotyledons typically exhibit a broad range of characteristics, including net-veined leaves, flower parts in multiples of four or five, and vascular tissue organized in a ring. Examples of dicotyledons include roses, sunflowers, and oak trees. They are one of the two main classes of angiosperms, the other being monocotyledons, which have one cotyledon.
