About

Syzygium thompsonii (Chamorro: atoto) is an endemic tree of the Mariana Islands of Guam, Rota, and Saipan with a striking appearance due to its abundance of white flowers and edible fruit that grow directly from the trunk. It is related to the Malay apple but bears smaller tart fruit.

Where it grows

Syzygium thompsonii is a canopy tree found in limestone forests. It is listed as endemic only to the 3 southernmost Mariana islands: Guam, Rota and Saipan. On Guam, the tree is only found in the northern limestone forest. The Smithsonian's US National Herbarium holds specimens from Saipan, collected from Water Cave and the north slope of Mt. Tapochau, It also holds specimens from Rota, collected from the limestone forest at the start of the last ascent into the savanna, and another from the high limestone area below the top cliffs of the western end of Rota.
