Marcgravia polyadenia Sleumer

Pacayacu Marcgravia (Marcgravia polyadenia 

The genus Marcgravia contains about 60 or 65 species which occur in South- and Central America.  


This species is known only based on the type material, which was collected in the 1930s in a primary forest near the town of Pacayacu in Ecuador.  

The original vegetation at the locality is now almost completely destroyed, and as the species was never found again, it may be extinct now.
