description
Vegetative characteristics
The evergreen tree reaches a height of about 10 m. The young twigs are hairy at first and later bald, older twigs are covered with lenticels . The egg-shaped, scaly-covered, approximately 1 cm long buds are downy-haired. The helically arranged leaves are stalked 2–3 cm long. The simple and undivided, pinnate leaf blade is ovate to ovate-elliptical and has a length of 7-10 cm and a width of 4-6 cm. It has a blunt or rounded, rarely almost heart-shaped base and is pointed at the front. The leathery blade is two-tone and bare. It has 10-14 pairs of bilateral protruding lateral nerves. The spreading edge is notched-sawn.
Generative characteristics
Nothing is known about the structure of the inflorescences and flowers .
The 2–3.5 cm long stalked fruit stands are approximately 2 cm wide and spherical with a truncated base. They consist of 10–18 capsules . The individual fruits are woody, two-compartment capsule fruits , which open in folds with two two-part flaps. The styles are no longer present in the fruit state. The seed coat is thick and hard. There is little endosperm .
Altingia multinervis flowers from March to May and fruit from June to August.
distribution and habitat
Altingia multinervis is only known from the north of the southern Chinese province of Guizhou (Chishui Xian).
The tree species grows in forests at approx. 1000 m above sea level .
Taxonomy
Altingia multinervis was described by the Chinese dendrologist Cheng Wan-Chun in 1947 . The first description was based on a single collection, the type collection . Altingia multinervis is considered a synonym of Altingia chinensis by some authors . According to R. Govaerts, the species is best placed as Liquidambar multinervis (WCCheng) Ickert-Bond & J.Wen in the genus Liquidambar .
etymology
The specific epithet multinervis ( Latin for many nerves ) is derived from Latin multum (a lot ) and Latin nervus ( nerve ). It apparently refers to the number of lateral nerves, which is higher than other Altingia species. The genus Altingia is named in honor of Willem Arnold Alting (1724-1800), the governor-general of the Dutch East Indies at the time when the first descriptor Francisco Noroña visited Java .
