French plane tree is a common name for a type (one, two, three) of hanging suzuki in the mainland, and its fruit ball, that is, the "bell" of hanging suzuki, is its fruit? What type of fruit is it?

When the fruit balls of the plane tree are ripe, they can be hung on the tree all winter without falling and fluttering in the wind, like strings of wind chimes.

However, in April and May of the following year, a lot of "hair" fell off the fruit balls, flying all over the sky, often making people miserable. Upon closer inspection, you can find that it is a hairy inverted cone-shaped small nut, its hair is grown upside down, that is, the hair is inside the fruit ball, and the outside is a layer of small nuts.

It seems that it is not a fruit, but a fruit order. I read a lot of articles, many people say that it is a polycarpure, in fact, this is not right, it should be a polyflora fruit. They are defined like this:

Aggregate fruit: It is developed from several isolated cardiac skin pistils in the flower, each pistil forming a single fruit, and most small fruits clustered on the same peduncle.

It can be seen that the aggregate fruit develops from a flower. According to the type of aggregate fruit single fruit, it can be divided into aggregate lean fruit (such as strawberry), polymer stone fruit (such as hanging hook), polymerized lotus fruit (such as star anise), aggregate nut (such as lotus).

Polyflowering fruit: The fruit that develops from the whole inflorescence is called polyflower, also called compound fruit. Such as mulberries, pineapples, figs, etc.

It can be seen that polyflora is developed from the entire inflorescence (inflorescence axis + many flowers born on it), and hundreds of flowers in the inflorescence each develop into a small fruit, which is gathered together on the inflorescence axis to form a compound fruit. The fruit of the plane tree develops from the entire cephalic inflorescence.
