Quercus franchetii, commonly known as the zhui lian li evergreen oak, is a species of oak in the section Quercus sect. Cerris, native to a wide area of eastern Asia. It is an oak native of China (Sichuan and Yunnan), northern Thailand and Vietnam where it grows at an altitude between 800 and 2600 meters.[2]
In nature, it forms an evergreen tree up to 15 m (50 ft) high.[2] Sometimes, it is shrubby. When older with an irregular and tortuous branches. The branches are covered with a creamy white tomentum very long lasting. The buds are small, globular with pointed apex, reddish and white ciliated edge.[2]
This species was described in 1899 and dedicated to Adrien René Franchet, a botanist at the Muséum national d'histoire naturelle in Paris. Franchet had a few months earlier named and described this species as Q. lanuginosa,[3] but his name turned out to have been used before, so Skan renamed it as Q. franchetii.[4] It is in the subgenus Quercus, it is in the section Cerris, resembling Q.lanata.
The leathery oval leaves measure 5 to 12 cm (2-4.5 in) long by 2.5 to 6 cm (1-2.4 in) wide, and are evergreen (remaining on the plant over winter). They have a cuneate (wedge-shaped) or slightly rounded base, and the upper surface is smooth and shiny, while the underside is densely covered with yellowish fur.[2] The leaf margin is dentate, with 5 to 10 pairs of short teeth, though not near the base, and the leaf sits on a 1–2 cm long furry grey-yellow petiole. The fruit is an acorn which measures 0.9-1.1 cm in length by 0.8 cm across; ovoid, apex depressed but mucronate; silky; short peduncle (1.5–3 cm); enclosed 2/3 by cup; cup 0.8-1.1 cm in diameter, scaly; maturing in 1o r 2 years.[2]
