I would say the Eucalyptus tree, planted all over the world but native to Australia, is quite unusual.
Young Eucalyptus trees have leaves that are rounded and are arranged opposite to one another. However, when mature the leaves of a Eucalyptus are lance-like and are arranged in an alternating fashion. This to me is quite unusual.

I like to imagine aliens visiting earth and walking straight past us and communing with Pando.
