The botanist's daughter? (5)
I believe the answer is:
flora
'the botanist's daughter?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
This is all the clue.
Can you help me to learn more?
(Other definitions for flora that I've seen before include "Plants of a region or age" , "Plant life of particular area" , "Botanical specimens" , "A region's plants" , "__ MacDonald, heroine of the 1745 Jacobite rising" .)
