Eros cut small flowers (5)
I believe the answer is:
roses
'flowers' is the definition.
(rose is a type of flower)
'eros cut small' is the wordplay.
'cut' indicates anagramming the letters (cut can mean mixed).
'small' becomes 's' (abbreviation - e.g. clothes size).
'eros' anagrammed gives 'rose'.
'rose'+'s'='ROSES'
(Other definitions for roses that I've seen before include "Fragrant flowers" , "These flowers in one's cheeks usually denote health" , "Flowers, usually red, pink, white or yellow" , "Occupants of bed" , "the wars" .)
