Rose, for example with worker in queue (9)
I believe the answer is:
eglantine
'rose' is the definition.
(eglantine is a kind of rose)
'example with worker in queue' is the wordplay.
'example' becomes 'eg'.
'with' is a charade indicator (letters next to each other).
'worker' becomes 'ant' (worker is a type of ant).
'in' is an insertion indicator.
'queue' becomes 'line' (I've seen this before).
'ant' going inside 'line' is 'lantine'.
'eg'+'lantine'='EGLANTINE'
'for' acts as a link.
(Other definitions for eglantine that I've seen before include "Rose, growing wild" , "Inelegant (anag.); wild rose" , "Wild rose, sweet briar" , "Inelegant sort of sweet-brier" , "Sweetbriar, inelegant in a way" .)
