There is a Set Piece known as a "Reed Trap", which is a patch thick with Reeds, but also thick with Tentacles, trying to harvest the Reed in this trap unprepared can result in death or serious injury.
- According to Wickerbottom, the reeds belong to the rush family Juncaceae, even though species in the family are not used to produce paper. The family Juncaceae is often confused with the sedge family Cyperaceae, which contains Cyperus papyrus (also known as Paper Reed), a plant the Ancient Egyptians used to create paper.
- The appearance of the Reed in-game, due to its telltale flower, suggests that the plant belongs to the cattail/reedmace family Typhaceae. This family includes the genus Typha, which is also used to produce paper.
