The floral organs keep the flower developing. The floral parts produce seeds. Grass has thread like roots called fibrous, stems called culms, joints called nodes, and areas between the joints called internodes. While nodes are solid, sometimes internodes are hollow. There are two kinds of stems, rhizomes and stolons.
Rhizomes are below ground creeping stems, and stolons are above ground creeping stems.
Grass leafs are two ranked, and grow on the opposite side of the culm of the leaf below. The leaf is made of the sheath, blade, ligule, and auricle. The sheath wraps around the culm above every node. The blade is flat and narrow, and attaches to the top of the sheath. The ligule grows where the blade and sheath meet, and may form a thin sheet.
