Pinus latteri
Template:Short description Template:Speciesbox
Pinus latteri, or Tenasserim pine, is a pine native to Mainland Southeast Asia.
DescriptionEdit
Pinus latteri is a medium-sized to large tree, reaching Template:Convert tall and with a trunk diameter of up to Template:Convert. The 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, Template:Convert long and just over Template:Convert thick, green to yellowish green. The cones are narrow conic, Template:Convert long and 4 cm broad at the base when closed, green at first, ripening glossy red-brown. They open to 6–8 cm broad, often some time after maturity or following heating by forest fires, to release the seeds. The seeds are Template:Convert long, with a Template:Convert wing, and are wind-dispersed.
Related speciesEdit
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. merkusii, which was described first), but the Sumatran pine differs in shorter (15–20 cm) and slenderer (under 1 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 habitatEdit
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 Template:Convert, but occasionally as low as Template:Convert and up to Template:Convert. The tree is named after the Tenasserim Hills between Myanmar and Thailand.
