'''''Pinus fenzeliana''''' commonly known as the '''Hainan white pine''' or '''Fenzel's pine''', is a [[tree]] [[endemic (ecology)|endemic]] to the island of [[Hainan]] off southern [[China]].<ref>{{EOL|991280|Pinus fenzeliana}}</ref> This [[pine]] reaches heights of 20 m<ref>{{cite web|url=http://www.discoverplants.com/plant-types/trees/hainan-white-pine/|title=Hainan White Pine Description_DiscoverPlants|access-date=2007-06-23|archive-date=2016-12-21|archive-url=https://web.archive.org/web/20161221002540/http://discoverplants.com/plant-types/trees/hainan-white-pine/}}</ref> with a trunk 1 m in diameter.

==Description== The [[leaves]] are needle-like, in [[fascicle (botany)|fascicles]] of five, and 5–13&nbsp;cm long. The [[seed cone]]s are 6–11&nbsp;cm long, with thick, woody scales; the seeds are large, about 8–15&nbsp;mm long, with a vestigial 3&nbsp;mm wing, similar to the related [[Chinese white pine]] (''Pinus armandii''). Hainan white pine differs from that species in the shorter needles, smaller cones, and in being adapted to a [[subtropical]] [[rainforest]] habitat.

A pine from the [[Dabie Mountains]] in [[Anhui]], eastern China, first described as a species ''[[Pinus dabeshanensis]]'', is occasionally treated as a variety of this species, but more commonly as a variety of ''P. armandii'', which it more closely resembles.

Reports of ''Pinus fenzeliana'' from [[Vietnam]] have not been verified; trees in this area have proved to be either [[Vietnamese white pine]] (''Pinus dalatensis'') or [[Guangdong white pine]] (''Pinus wangii''), which both differ markedly in cone and seed size and shape, though similar in foliage.
