Notes on Meaning

• The term "holm" in this context is an archaic word for a small island or a piece of flat land by a river or in a fen. The name "sea holm" likely refers to the plant's habitat on coastal dunes, which can resemble small, isolated patches of land. It is crucial to distinguish this specific plant name from the general term "holly," as they are unrelated species.
