Maybe yew produced fir cone (7)
I believe the answer is:
conifer
'maybe yew' is the definition.
(yew is an example)
'produced fir cone' is the wordplay.
'produced' is an anagram indicator.
'fir'+'cone'='fircone'
'fircone' anagrammed gives 'CONIFER'.
(Other definitions for conifer that I've seen before include "Tree such as pine, yew etc" , "one branching out" , "Fir or pine, for example" , "E.g. yew, pine or fir" , "Evergreen (generally)" .)
