The spongy mesophyll and pallisade mosophyl layers form the middle layers of the leaf. The pallisade mesophyl contains many tightly packed cells which do photosynthesis. The spongy mesophyl contains mainly hollow space, allowing for gas exchange.

Palisade most likely is refering to the Palisade Mesophyl, which is a tissue layer within a leaf, it sits below the epidermis layer (which is the outermost layer on top of a broad leaf) and contains chloroplasts. Below it is the Spongy mesophyl.
