Dried plants in that woman's element (9)
I believe the answer is:
herbarium
'dried plants in' is the definition.
The definition suggests a singular noun which matches the answer.
'woman's element' is the wordplay.
'woman' becomes 'her' (her refers to a woman).
'element' becomes 'barium' (barium is a kind of element).
'her'+'barium'='HERBARIUM'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for herbarium that I've seen before include "Flora preserved" , "Where Rosemary, for one, is" , "Plant room" .)
