A gumnut is the woody fruit of certain species of eucalyptus trees, commonly found in Australia. These small, cup-shaped structures contain seeds and are often seen hanging from the branches of the tree. Gumnuts are an important part of the eucalyptus life cycle, as they protect the seeds until they are ready to be released. Gumnuts are also popular in Australian culture and are often depicted in art and literature. They are associated with the Australian bush and are featured in the works of May Gibbs, a famous Australian author and illustrator known for her stories about the gumnut babies.
