The Ginkgo family, properly known as Ginkgoaceae, is unique because it only has one living member: the Ginkgo biloba tree. Imagine a family where everyone else moved away, leaving only one person to carry on the name. That's the Ginkgo family. This makes it a 'monotypic' family in botanical terms, meaning it consists of a single species. It's like a band where only one musician remains.
