In the grass family,the cotyledon is called the scutellum,which is situated toward one side (lateral) of the embryonal axis.At its lower end,the embryonal axis has the radicle and root cap enclosed in an undifferentiated sheath called the coleorhiza.The portion of the embryonal axis above the level of attachment of the scutellum is the epicotyl. The epicotyl has a shoot apex and a few leaf primordia enclosed in a hollow structure called the coleoptile.
