Dendroseris neriifolia

Sonchus neriifolius, synonym Dendroseris neriifolia is a species of flowering plant in the family Asteraceae. It is a tree with droopy, elongated leaves and small yellow-white flowers. The plant was originally native to Continental Chile but is now endemic to Robinson Crusoe Island.

The plant is endangered and very rare: only two specimens are known to exist in a ravine in the eastern part of the island, although there exist other human-cultivated specimens. It is classified as critically endangered by the World Conservation Monitoring Centre. In a collaboration between the Millennium Seed Bank (MSB) at Kew Wakehurst near Haywards Heath and the National Forest Corporation (CONAF) with Parque Nacional Archipiélago Juan Fernández (PNAJF) 29 seeds were sent to Kew, of which eight are now germinating.

Three will be sent to Logan Botanic Garden in Scotland once they are big enough. The other 21 seeds will be put in long-term storage at the MSB at Kew.

This endemic shrub inhabits the montane forests and subalpine zones of the Juan Fernández Islands, typically growing on steep volcanic slopes and ridges at elevations between 400-900 meters. It occurs in areas with high humidity and frequent cloud cover, often associated with native Myrceugenia forests and other endemic island vegetation.
