Class monocotyldonae is unique for multiple reasons. First, the seds only contain one cotyledon, the thing that becomes the first leaves of a seedling. Also, the leaves have parallel veins and the flower parts are usually in multiples of three. Monocotyldonae lack cambium, a layer of actively dividing cells, and have scattered vascular bundles in the stem. Finally, all of them are generally wind pollinated and the majority are herbaceous. This means that after season the stems and leaves will die down to ground level.
