Pinus merkusii, the Sumatran Pine. is closely related to the Tenasserim Pine - Pinus latteri, which occurs further north in southeast Asia from Myanmar to Vietnam; some botanists treat the two as conspecific (under the name Pinus merkusii, which was described first), but Pinus latteri differs in longer (18-27 cm) and stouter (over 1 mm thick) leaves and larger cones with thicker scales, the cones often remaining closed for some time after maturity.
