Dracaena cambodiana is a narrow-distributed species, which is found in Yunnan, Guangxi, and Hainan provinces in China, Laos, Vietnam, Thailand and Cambodia. It is commonly known as Cambodian dragon tree or dragon blood tree. In 2001, D. cambodiana was listed as an endangered species due to its highly restricted distribution and overexploitation.
