Vernonia ledocteana P. A. Duvign. & Van Bockstal

Copper Vernonia (Vernonia ledocteana)  

This remarkable highly specialized plant species was endemic to the Democratic Republic of the Congo, where it was restricted to copper-rich soil.  

The species disappeared, together with several other highly specialized species, due to habitat loss by copper mining. [1]

Vernonia sechellensis Baker

Seychelles Vernonia (Vernonia sechellensis)

The Seychelles Vernonia was endemic to the island of Mahé, Seychelles Islands, it is known only from the holotype, which had been collected in 1874 in the so called Forêt Noire, an area that appears to have been largely deforested since then.

The Seychelles Vernonia was a very small shrub, reaching only about 1,2 m in height.

The species was never found since 1874 and is clearly extinct.
