Distribution and habitat

This small tree was once endemic to Isla Más a Tierra (Robinson Crusoe Island) where it grew between Sector Puerto Francés and Quebrada Rabanal with an area of occurrence of less than 10 km2 . It was even reported as a rare species in the 1890s by the botanist Federico Johow and almost a century on in the 1980s only a single individual survived in Puerto Francés (Ricci,1989). Subsequent searches over a period of 15 years failed to find any plants remaining in the wild. Historically this species was cut by early colonizers and taken to Europe to be used as incense for Churches, it was also used for medicinal purposes (Johow 1896). Grazing by cattle, sheep, goats, and rabbits further decimated the population.
