Cotyledon

This seedling germinated producing two plain-looking cotyledons later followed by two normal-looking leaves that are small copies of the adult leaves.

Seed-leaf; the primary leaf or leaves in the embryo; in some plants the cotyledon always remains in the seed-coats and in others (as bean) it emerges on germination.
