Unidentified seeds that fly with long silky threads. Long tuft of hair on the seed help to catch the wind and enable seed to fly far away.

Alsomitra macrocarpa
The winged seed of Alsomitra macrocarpa

Alsomitra macrocarpa's common name is Javan cucumber. Origin of Indonesia, Borneo Island

The winged seeds of the Javanese cucumber are the largest floating seeds in the world.

By hovering like a butterfly, they can bridge enormous distances. Even without wind in a rainforest the seeds can be spread to a distance.

The species is featured in the BBC documentary Life and drew the attention of several scientists who study aerodynamics and aircraft movements.

The plant grows as a vine and belongs to the gourd family. The fruits are as big as a football, quite remarkable on its own.

The Alsomitra Vine grows from the forest floor and up the surrounding trees to the highest point it can reach.
Once it is high above the forest floor, it begins developing a football-sized pod. In this pod there are around four hundred seeds.
The problem is, if all of these seeds just feel to the forest floor, all of these vines would have to complete for soil nutrients and sunlight. So, it is vital for this vine to send these seeds off as far as possible. The way this issue is overcome is by flight. Each seed is encased in a clear, lightweight, perfectly designed glider (See the picture above). Once the vine’s seedpod is opened, these seeds are able to travel hundreds of feet, or more, depending on the wind.

In the early 1900s, inventers such as Igo Etrich and the Horton brothers used this seed to help create gliders and aircrafts. About 20 years ago, two Japanese engineers studied this seed and realized its design was absolutely incredible. In fact, this seeds shape has led to the design of some of our modern day “flying wing” aircrafts like the stealth bomber.
