Tegmen corresponds to which layer of the seed coat?

Explanation:
The seed coat has two integuments from the ovule: the outer integument forms the testa, and the inner integument forms the tegmen. So, the tegmen is the inner seed-coat layer, lying just inside the testa. The endosperm is the nutrient tissue inside the seed, and the aleurone layer is a part of that endosperm, not part of the seed coat. Therefore, tegmen correctly corresponds to the inner seed coat layer.
