'''''Pinus latteri''''', or '''Tenasserim pine''', is a [[pine]] native to [[Mainland Southeast Asia]].

==Description== ''Pinus latteri'' is a medium-sized to large [[tree]], reaching {{Convert|25–45|m|abbr=off}} tall and with a trunk diameter of up to {{Convert|1.5|m|ft|abbr=on|frac=2}}. The [[Bark (botany)|bark]] is orange-red, thick and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The [[leaves]] ('needles') are in pairs, moderately slender, {{Convert|15–20|cm|abbr=off|frac=2}} long and just over {{Convert|1|mm|frac=32}} thick, green to yellowish green. The [[conifer cone|cones]] are narrow conic, {{Convert|6–14|cm|abbr=on|frac=4}} long and 4&nbsp;cm broad at the base when closed, green at first, ripening glossy red-brown. They open to 6–8&nbsp;cm broad, often some time after maturity or following heating by [[wildfire|forest fires]], to release the seeds. The seeds are {{Convert|7–8|mm|abbr=on|frac=32}} long, with a {{Convert|20–25|mm|abbr=on|frac=32}} wing, and are wind-dispersed.

===Related species=== ''Pinus latteri'' is closely related to [[Sumatran pine]] (''Pinus merkusii''), which occurs further south in [[Southeast Asia]] in [[Sumatra]] and the [[Philippines]]; some botanists treat the two as conspecific (under the name ''P.&nbsp;merkusii'', which was described first), but the Sumatran pine differs in shorter (15–20&nbsp;cm) and slenderer (under 1&nbsp;mm thick) leaves, smaller cones with thinner scales, the cones opening at maturity, and seeds only half the weight. It is also related to the group of [[Mediterranean]] pines including [[Aleppo pine]] and [[Turkish pine]], which share many features with it.

==Distribution and habitat== It grows in the mountains of southeastern [[Burma]], northern [[Thailand]], [[Laos]], [[Cambodia]], [[Vietnam]], and [[Guangxi]] Province and [[Hainan]] island of [[China]].<ref name = powo/>

It generally occurs at moderate elevations, mostly from {{Convert|400–1000|m|abbr=on}}, but occasionally as low as {{Convert|100|m|abbr=on}} and up to {{Convert|1200|m|abbr=on}}. The tree is named after the [[Tenasserim Hills]] between Myanmar and Thailand.
