This species is confined to the southwest coast of San Cristóbal Island  in the Galapagos. The single subpopulation, representing a single location, has an extent of occurrence (EOO) and an area of occupancy (AOO) of ca 4 km². Continuing declines are inferred and projected due to habitat loss and damage caused by herbivory and tourism. Therefore, this species is assessed as Critically Endangered.
Previously published Red List assessments:
1998 Endangered (EN)

Population [top]

Population: The subpopulation at La Loberia in 1998 was estimated at 200-300 plants but not all of these were mature individuals. The subpopulation is now much larger than this and extends further east, but represents a single location. The population has declined and is now small but apparently stable.
Current Population Trend: Stable
Additional data:
Continuing decline of mature individuals: Yes

Habitat and Ecology [top]

Conservation Actions [top]

Conservation Actions:

The Galapagos Islands are almost entirely designated as a national park (El Parque Nacional de Archipiélago de Colon). In 1968, 97% of the land in the archipelago was included in the park. In 1978, it was recognised as a UNESCO World Heritage Site and in 1984, a UNESCO-MAB Biosphere Reserve. Goat eradication programmes are ongoing throughout the Galapagos.
