Gone but not forgotten
Kew and local conservationists collected cuttings from the last known wild plant before it died in 1994.
In 2003 the last surviving individual in cultivation succumbed to a devastating termite attack and fungal infections.
No living material could be salvaged, but sample of its genetic material (DNA) was collected for storage in Kew’s DNA bank. Fortunately, this precious resource is still available for research.
Nesiota elliptica is the only species in the genus Nesiota, so that the genus also disappeared with the extinction of the species in 2003.
