The paper provides updated and thoroughly databases on vascular flora and vegetation types at elevational belt over 2800m of Hoang Lien Son mountain range (Lao Cai province) for plant - diversity conservation and sustainable development planning. The research results show that this flora includes 126 species, 82 genera, 46 families belonging to 3 vascular divisions: Polypodiophyta, Pinophyta and Magnoliophyta. In particular, Magnoliophyta has absolute dominance with 123 species (accounts for 97.6% of the total species of study area). The flora of research area has 6 valuable and rare species (5% of total species) in Vietnam Red Book, Red List of IUCN; 13 endemic species (10.3% of total species) and 37 useful species (29.4% of total species). Among them, there are 7 endemic species only in Hoang Lien Son area, 31 medicinal species, 9 ornamental species and 5 food species. The vegetation of the study area consists of 5 formations. These are typical and unique vegetations of Hoang Lien Son high mountain area that should be prioritized to protect from human impacts, especially overload tourism development.
