June 2009. Photos were sent to PestNet of a grafted Adenium obesum plant showing splitting of the bark and extensive "corking", presumably subersisation. The symptoms are now iadvanced, on this plant which is said to have been grafted - no details given.

It is likely that the plant is showing signs of graft incompatibility, and it was suggested that a search of the Internet would find references to such symptoms, possibly in Adenium.
