phelloderm
This term is a highly specialized botanical descriptor used almost exclusively in plant anatomy and histology. It refers to the living tissue layer that supports the development of the periderm, the protective outer bark of woody plants. Because it describes a specific biological structure, it is used in a technical, scientific register rather than in general conversation.
In a botanical context, it is often discussed alongside the phellem (cork) and phellogen (cork cambium). Together, these three components constitute the periderm. The phelloderm is distinguished by its role as the innermost layer, consisting of parenchyma cells that provide structural and metabolic support to the outer tissues.
Meanings
Examples

Look closely at the slide to see the phelloderm layer just inside the phellogen.
I wonder if the phelloderm in this species differs from that of the oak tree.
The phelloderm provides a secondary cortex for the woody stem.
Is the phelloderm always present in all dicotyledonous plants?
The cells of the phelloderm are typically thin walled and living.
The phelloderm is produced toward the inside of the stem during secondary growth.
We must distinguish between the primary cortex and the phelloderm.
