what kind of tree is it?

Chinese famous bottle tree, also known as Buddha's belly tree, spindle tree, radish tree, dried bottle tree, water storage tree, Malvaceae spindle tree and bottle tree, originated in South America and mainly distributed in the Brazilian plateau of South America. ? It grows in the Amazon river basin in northern Brazil, which is hot and rainy and belongs to the tropical rainforest area. The south and east have long dry season, dry climate and dry soil, which are savanna belts. Being in a tropical rain forest (tropical sparse forest), there are rainy and dry seasons in a year, but the rainy season is shorter.

Bottle trees, like tourist bananas, can provide water for travelers in the desert. As long as people dig a small hole in the tree, fresh thirst-quenching "drinks" can flow out continuously to solve people's urgent need for water in the vast sand sea.
