19d Handkerchief concealing daughter's hand, partly

?A?A?A

so I think it must be banana derived from bandana but not sure about the rest of the parsing?

a bunch of bananas is called a hand

ban(D)ana

remove d for daughter.

ps, the partly means there is only one. hence the singular 'banana'

The banana fruits develop from the banana heart, in a large hanging cluster, made up of tiers (called "hands"), with up to 20 fruit to a tier. The hanging cluster is known as a bunch, comprising 3–20 tiers, or commercially as a "banana stem", and can weigh 30–50 kilograms (66–110 lb).
