Kind of plant seen in the woman's book (4)
I believe the answer is:
herb
'kind of plant' is the definition.
'the woman's book' is the wordplay.
'the woman' becomes 'her' (**).
'book' becomes 'b'.
'her'+'b'='HERB'
'seen in' is the link.
(Other definitions for herb that I've seen before include "Wayside plant with small red flowers" , "Chives or coriander, say" , "Marjoram, say" , "Eg, sage" , "Rosemary, for example" .)
