1A9331E7C13E57E89DFA4FD63DBF3C91.taxon	etymology	Etymology. This hornbeam from southeast Yunnan has extremely large bracts, which are distinctly different from other closely related hornbeams, and therefore is given the epithet gigabracteatus.	en	Lu, Zhiqiang (2020): Carpinus gigabracteatus, a new species from southeast Yunnan, China.
