A single germinating nut of a tree identified as
Vatica stapfiana was planted in January 2014 in a polybag with topsoil in 50% shade at the nursery of INTROP-UPM. The species is considered as endangered by the IUCN.

The picture has been taken in June 2014 and shows a seedling that has stopped its growth. One reason could be the fact that the root tip has been damaged during plantation. To my opinion, the main reason is that this species needs specific conditions maybe the presence of other species or a soil containing a network of some specific ectomycorrhizal fungi.
Another
Vatica stapfiana has been spotted and the growth of new seedlings should be tested.
