An ear ( Spica ) is an unbranched inflorescence with an elongated main axis, the spindle ( Rhachis spicae ). If this main axis is fleshy, it is called a piston ( spadix ). The single flowers are sessile on the spindle of an ear. In most ears, the lowest flowers bloom first ( basitonia ).

Modifications to the basic plan

Occasionally there are transitional forms to the grape , which are characterized by stalked flowers. For example, in the genus of the twisted root there are indistinct flower stalks on the lower flowers.

In sweet and sour grasses, there are spikelets instead of individual flowers.
