Woman captivated by green ideals (4)

I believe the answer is:

enid

'woman' is the definition.
(woman's name)

'captivated by green ideals' is the wordplay.
'captivated by' says the answer is hidden in the clue.
'ENID' can be found hidden inside 'green ideals'.

(Other definitions for enid that I've seen before include "Arthurian wife" , "Miss Blyton" , "- Blyton, children's writer" , "Dine out on this girl's name also" , "'... Blyton, children's author (4)'" .)

I've seen this clue in The Irish Times.
