English: Tatiman Passage in the northwest of the Atoll is the only navigable entrance into the lagoon of Nikumaroro (formerly Gardner Island), Phoenix Islands, Kiribati. Original field notes: Showing tree heliotrope (far right). All mounded vegetation on atolls is native. The introduced, most important food plant, coconut palm, tends to have a tall, spiky look.
