Identification: Characteristics of Grasses
Collar (grasses)
The collar region of the leaf blade is most useful for identifying grasses before they flower (flower heads may provide a more obvious means for identification). The collar marks the junction between the blade and the outer sheath on the outside of the leaf. It consists of the leaf blade, sheath, ligule, and auricles. These parts vary in appearance according to plant species, and therefore are used in identification.
