intine
Quick Summary
The intine is the inner, primarily cellulose wall of certain spores and, most notably, pollen grains. This delicate layer is situated within the exine, which is the outer, more rigid layer of the pollen grain's wall. The intine plays a role in the pollen grain's structure and development. Its composition of cellulose allows for flexibility, which is important during germination when the pollen tube emerges. The term "intine" originates from Latin, meaning "within," reflecting its position inside the pollen grain.1

pollen…are an inner layer, the intine, and an outer layer, the exine. The intine consists, at least in part, of cellulose or hemicellulose. The outer and most durable layer, the exine, is very resistant to disintegration; treatment with intense heat, strong acids, or strong bases has little effect upon it.…
