| | The '''Ginkgo''' ('''''Ginkgo biloba'''''; ''''銀杏'''' in Chinese), frequently misspelled as "Gingko", and also known as the '''Maidenhair Tree''', is a unique [[tree]] with no close living relatives. It is classified in its own division, the '''Ginkgophyta''', comprising the single class '''Ginkgoopsida''', order '''Ginkgoales''', family '''Ginkgoaceae''', genus '''''Ginkgo''''' and is the only [[extant|extant species]] within this group. It is one of the best known examples of a [[living fossil]]. In the past it has also been placed in the divisions [[Spermatophyta]] or [[Pinophyta]]. Ginkgo is a [[gymnosperm]]: its seeds are not protected by an [[ovary (plants)|ovary]] wall. The apricot-like structures produced by female ginkgo trees are technically not [[fruit]]s, but are the seeds having a shell that consists of a soft and fleshy section (the [[sarcotesta]]), and a hard section (the [[sclerotesta]]). | | The '''Ginkgo''' ('''''Ginkgo biloba'''''; ''''銀杏'''' in Chinese), frequently misspelled as "Gingko", and also known as the '''Maidenhair Tree''', is a unique [[tree]] with no close living relatives.

| | For centuries it was thought to be extinct in the wild, but is now known to grow wild in at least two small areas in [[Zhejiang]] province in eastern [[China]], in the [[Tian Mu Shan Reserve]]. However, as this area has known human activity for over a thousand years, the wild status of ginkgos there is uncertain. | | For centuries it was thought to be extinct in the wild, but is now known to grow wild in at least two small areas in [[Zhejiang]] province in eastern [[China]], in the [[Tian Mu Shan Reserve]].
