Lotus Berthelotii

This beautiful flower has been classified in the category of endangered since 1884. This flower is actually believed to have become extinct in the wild. This amazing plant is endemic plants found in the Canary Islands. Pollination of this flower is believed to be assisted by a bird sunbird, which has long been known to become extinct in the Canary Islands. This may help to explain the scarcity of this plant. The trial was conducted to find new pollinators for these flowers, in the hope that they can be successfully reintroduced to the Canary Islands, but in 2008, no fruit was produced at all
