The outer olfactory organs somewhat recall a small flower (6)
I believe the answer is:
floret
'a small flower' is the definition.
(I've seen this before)
'the outer olfactory organs somewhat recall' is the wordplay.
'FLORET' is hidden back-to-front in amongst the letters.
But, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for floret that I've seen before include "Part of a cauliflower or broccoli head" , "Small flower" , "Piece of broccoli" , "Part of cauli head" , "Broccoli stem" .)
