The ear is a spike, consisting of a central stem on which tightly packed rows of flowers grow. These develop into fruits containing the edible seeds. In corn, it is protected by leaves called husks. In some species (including wheat), unripe ears contribute significantly to photosynthesis, in addition to the leaves lower down the plant. A parasite known as "Anguina tritici" (Ear Cockle) specifically affects the ears on

These were often backed by specimens deposited in a herbarium which was a collection of dried plants that
