What is "bretschneidera"

Bretschneidera sinensis, the sole species in genus Bretschneidera, is a rare, tall tree with large inflorescences. It is found in south and east of China, Taiwan, northern Thailand and northern Vietnam. It is threatened by habitat loss. Because of its relatively recent discovery in Taiwan and Thailand, it is possible that it could also be found in Laos and northern Myanmar. It was named in honor of Emil Bretschneider.

In Thailand it is known as Chompoo Phu Kha and is found only on Doi Phu Kha National Park in the Luang Prabang Range where it flowers in February and March.

The taxonomic position of genus Bretschneidera is enigmatic, and it has also been placed in its own family, Bretschneideraceae.
