Eyes - A darker colored zone on the petals and sepals of the flower just above the throat. Notice that in the examples below the eye color also appears on the sepals. If the dark color only appears on the petals, it as called a band.

Edges refer to the outer periphery of the petals and occasionally the sepals.

Edges can be structural, i.e. have knobs, braids, tentacles, fringe, and teeth.

Edges can also be of a different color. If the edge is narrow and gold, silver, or white, it is referred to as a wire edge.

Edges of a different color or colors can be narrow (referred to as a picotee) or wide (referred to as a border).

Some structural edges reach down into the surface of the flower. These super sculpted edges give a three-dimensional quality to the flower.
