Shrub found in African wilderness (4)
I believe the answer is:
bush
I believe this is a triple definition!
'shrub' is the first definition.
(I know that shrub can be written as bush)
'found in' is a link.
'african' is the second definition.
(I have seen 'Rural African' mean 'bush' so perhaps 'african' could also mean 'bush')
'wilderness' is the third definition.
(I know that bush is a type of wilderness)
(Other definitions for bush that I've seen before include "Shrub; hole lining" , "Remote country" , "Shrub; wild vegetation" , "Shrub; metal lining" , "ex-president" .)
