Flowering shrub a couple of accountants found around island (6)
I believe the answer is:
acacia
'flowering shrub' is the definition.
(I've seen this in another clue)
'a couple of accountants found around island' is the wordplay.
'couple of accountants' becomes 'CA CA' (CA can stand for chartered accountant).
'found around' means one lot of letters goes inside another.
'island' becomes 'i' (geographical abbreviation).
'caca' going around 'i' is 'cacia'.
'a'+'cacia'='ACACIA'
(Other definitions for acacia that I've seen before include "flowering plant" , "Shrub of warm climates" , "Thorny flowering shrub" , "Locust tree the false one" , "source of gum arabic" .)
