Ceiba boliviana, over here known as "paineira-rosa", occurs on a vast territory including Brasil, Bolivia and Paraguay. It has a very particular way of spreading its seeds. After pollination, big "bulbs" are formed. They contain the seeds that are surrounded by a cotton bed. Once the bulbs dry, they open up and the wind then takes care of flying "cotton parachutes" with seeds inside them. If they fall over an appropriate ground, the cotton provides shelter and humidity for the seeds to germinate and thus the species is preserved. It took more than a year (and many many photos) to finish this series. I hope you enjoy it!
