Graeme Carroll back with some floral inflorescence (6)
I believe the answer is:
raceme
'some floral inflorescence' is the definition.
'raceme' can be an answer for 'inflorescence' (raceme is a kind of inflorescence). I'm not sure about the 'some floral' bit.
'graeme carroll back with' is the wordplay.
'with' indicates a hidden word.
'back' says the letters should be written backwards.
'emecar' is hidden within 'graeme carroll'.
'emecar' reversed gives 'RACEME'.
Can you help me to learn more?
(Other definitions for raceme that I've seen before include "Long cluster of flowers along the main stem" , "Elongated cluster of flowers along a main stem" , "Long cluster of flowers on one stem" , "Flowers evenly spaced along central stem" , "something flowery" .)
