Widely scattered (6)
I believe the answer is:
sparse
'widely scattered' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sparse that I've seen before include "In short supply" , "Meagre, thin on the ground" , "Thinly dotted about" , "Infrequent" , "Thinly scattered, not dense" .)
