The translation of
Japanese terms can be a bit confounding. For example, the title of this
series is Edo no hana zukushi which can be translated as "The List of
Beauties of Edo." However, the word hana can mean either "a flower"
or (by extension) "a beautiful woman." This explains the pairing of the two
major elements of this print.
An afterthought: The linking of women with flowers must be fairly
universal. In the West it is not uncommon for a woman to be named Rose,
Lily, Iris, Daisy, Violet, Jasmine, etc.
