"Pseudolarix" is a monotypic genus in the family Pinaceae. The sole species, "Pseudolarix amabilis" is commonly known as Golden Larch, though it is not a true larch ("Larix"), being more closely related to "Keteleeria", "Abies" and "Cedrus". It is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of 100-1500 m. Golden Larch is sometimes known under an old scientific name "Pseudolarix kaempferi", but this may cause confusion with "Larix kaempferi", the Japanese Larch.

It is a deciduous tree reaching 30-40 m tall, with a broad conic crown. The shoots are dimorphic, with long shoots and short shoots similar to a larch, though the short shoots are not so markedly short, lengthening about 5 mm annually. The leaves are bright green, 3-6 cm long and 2-3 mm broad, with two glaucous stomatal bands on the underside; they turn a brilliant golden yellow before falling in the autumn, whence the common name. The leaves are arranged spirally, widely spaced on long shoots, and in a dense whorl on the short shoots.

The cones are distinctive, superficially resembling a small globe artichoke, 4-7 cm long and 4-6 cm broad, with pointed triangular scales; they mature about 7 months after pollination, when (like fir and cedar cones) they disintegrate to release the winged seeds. The male cones, as in "Keteleeria", are produced in umbels of several together in one bud.

Uses

Golden Larch is a very attractive ornamental tree for parks and large gardens. Unlike the larches, it is very tolerant of summer heat and humidity, growing very successfully in the southeastern United States where most larches and firs do not succeed. In Europe growth is most successful in the Mediterranean region with notable specimens in northern Italy; further north in Britain it will grow, but only very slowly due to the cooler summers there.

Medicinal use

Golden Larch is one of the 50 fundamental herbs used in Chinese herbology, where it is called "jīn qián sōng" ().
