Options

• Scar-like layer derived from funicle

• Fleshy, edible middle layer derived from nucellus

• Thin, membranous inner layer derived from inner integument

The tegmen is the thin, membranous inner layer of the seed coat that develops from the inner integument of the ovule. It lies beneath the tough outer testa and provides additional protective covering.
