periderm
Woody plant skin
Periderm is the protective outer layer of bark on woody plants, replacing the epidermis as stems and roots thicken with age.
It consists of cork cells that insulate and waterproof the plant.
In anatomy, periderm refers to the temporary outer skin layer on a fetus, shed before birth.
