Flowery greetings from simple islanders (4)
I believe the answer is:
leis
'flowery greetings' is the definition.
(I've seen this in another clue)
'from simple islanders' is the wordplay.
'from' says the answer is hidden in the clue.
'LEIS' is hidden in the letters of 'simple islanders'.
(Other definitions for leis that I've seen before include "Isle (anag) - Polynesian garlands" , "Hawaiian garlands" .)
