The winged seed of the tropical Asian
climbing gourd Alsomitra macrocarpa is remarkable. The entire seed has
an average wingspan of 5 inches and is capable of gliding through the
air of the rain forest in wide circles. This seed inspired the design
of early aircraft and gliders.
The wings are very thin film with wrinkles help the seed pick up lift
when flying at a low speed. The seed is located toward the front from
the center, which makes a perfect centroid for gliding through the air.
The climbing gourd plant Alsomitra
macrocarpa is native to the Sunda Islands of the Malay Archipelago,
produces one of the largest winged seeds up to 5 inches wide inside a
football size club-shaped gourd. The football-sized gourds hang from a
vine high in the forest canopy, each gourd packed with hundreds of
winged seeds.
