What is the persistent nucellus in the black pepper called?

Perisperm

The persistent nucellus in black pepper is called the perisperm. It is a tissue that is derived from the nucellus, which is the central part of the ovule. In most seeds, the nucellus is consumed by the developing embryo, but in black pepper, it persists and becomes the perisperm. The perisperm is a source of food and support to the developing embryo within the seed.
