Tardieu’s Spurge (Euphorbia tardieuana)  

This species is known exclusively from the type collection made in 1927 in the evergreen forests in the area around the two rivers Mangoro and Nosivolo at Madagascar’s east coast.  

The species appears to have never been found since, and since the type locality is now highly degraded, it may be completely extinct.  

***

There exists the chance that Tardieu’s Spurge is identical with another spurge species, Mangelsdorff’s Spurge (Euphorbia mangelsdorffii Rauh.), a species that is quite well known and often kept in cultivation.
