Can you guess these flowers?

Can you guess these flowers?

I don't think the flowers in the second pic have opened yet.
There's 2 flowers in the jackfruit pic.
The big one is the female flower which if pollinated will turn into a 7+ KG fruit. The little bud is the male flower, containing pollen.
Amaranth and Jack fruit
Great guess but 1 is not correct
Probably wrong but is it a pistachio?
Mango & jackfruit
Never would have got that 🙂. That is super interesting I am surprised it has so many flowers for a single seeded fruit.
Most won't pollinate & start forming baby fruit. Most of the baby fruit won't set & grow full sized.
This is the delicate few weeks as a quick spring storm can knoxk off both the flowers and baby fruits.
I should see little green fruit forming in the next couple of weeks hopefully. This is from a young Nam Doc Mai (Thai) tree I planted about 3 years ago. It had just 1 little mango on it last year.
