ABSTRACT
This paper presents some results of research on the diversity of Euphorbiaceae in Pu Huong Nature Reserve, Nghe An province, from May 2019 to June 2021. Total 79 species belonging to 31 genera of Euphorbiaceae family were collected and identified. There were 1 genera and 12 species found as new records for the plant list of Pu Huong published in 2016. The number of useful plant species of the Euphorbiaceae is categorized as follows: 45 species as medicinal plants, 17 species for timber, 12 species for edible plant, 6 species for fatty oil, 5 species for essential oil, 4 species for ornamental plant and 3 species for other.
The Spectrum of Biology (SB) of the Euphorbiaceae in Pu Huong is summarized, as follows:SB = 91.14% Ph + 3.80% Ch + 5.06 Th. The family of Euphorbiaceae in Pu Huong Nature Reserve is mainly comprised of the Asian tropical element (55.70%), endemic element (18.99%), ancient tropical elements (11.39%), temperate element (2.53%), intertropical element (2.53%) and crops element (7.59%), and world element (1.27%).
