Global Range
Bobea timonioides is endemic to the state of Hawaii. It has been documented on the islands of Kauai, Oahu (on both of the two mountain ranges), and Hawaii. On Maui, no b. Timonioides has been collected, but some Maui specimens appear to be hybrids between b. Timonioides and b. Sandwicensis (darwin and chaw 1990).

Abundance
There may be fewer than 300 trees of b. Timonioides remaining in Hawaii (j. Lau pers. Comm., 2000).

Global Threats
Threats to the species include fire, alien plants, ungulates, and an alien insect (the black twig borer). On the island of Hawaii it is additionally threatened by ranching and agriculture. Also on the island of Hawaii, many individuals have been destroyed over the past few decades by volcanic activity.

Permanence
Perennial.
