One of two major divisions of the angiosperms (a group of plants characterized by having ovules borne in ovaries), bearing only one cotyledon or seed leaf, for example, the grasses, lilies, bromeliads, orchids, and palms.
Angiosperms having one cotyledon (seed leaf); the leaves are usually parallel-veined, and floral parts are in threes.
A plant with a single seed-leaf, a natural group also characterised by lack of secondary xylem, the presence of parallel veins and trimerous flowers.
A plant having one seed leaf (cotyledon); one of the two major divisions of flowering plants.
Flowering plant in which the embryos have one seed leaf, often recognised by their trimerous flowers and parallel veins although there are many exceptions.
One of the two major subdivisions of the flowering plants (the other, larger one is the dicotyledons). Characterized by a single seed leaf, leaves mostly with parallel veining, and flower parts in threes or sixes. Major groups of monocotyledons are the grasses, sedges, lilies, orchids and palms.
