botany by classifying all monocotyledons as flowering plants with:
two seed-leaves in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5
one seed-leaf in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5
one seed-leaf in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6
two seed-leaves in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6
