Acer buergerianum - Trident Maple; Chinese: 三角枫 san jiao feng) is a species of maple native to eastern China (from Shandong west to southeastern Gansu, south to Guangdong and southwest to Sichuan) and Taiwan. It is a small to medium-sized deciduous tree reaching a height of 5-20 m with a trunk up to 50 cm diameter. The leaves are in opposite pairs, 2.5-8 cm long (excluding the 2-5 cm petiole) and 3.5-6.5 cm broad, hard, glossy dark green above, paler below, usually with three lobes; on mature trees the lobes forward-pointing and with smooth margins, on young trees with more spreading lobes and serrated margins. The flowers are produced in spring, yellow-green, in pendulous corymbs; they are small, with five greenish sepals and five yellow-white petals about 2 mm long, and eight stamens. The fruit is a samara with two winged seeds, each seed 4-7 mm diameter, with a 15 mm wing; the wings are forward-pointing and often overlapping each other.
