ABSTRACT
Species composition and the distribution of wetland plants
in Due Hue district, Long An province
An assessment of floral diversity in Due Hue district, Long An province, was carried
out. The survey results identified 155 species, 119 genera, 66 families belonging to the two
phyla of vascular plants including Polypodiophyta and Magnoliophyta, among which were
135 species (87.1% of the total) considered as medicinal plants (113 species), vegetables

(26 species), ornamental plants (15 species)... Two species were listed for conservation by
Vietnam Red Data Book, Part II, Plants (2007). The distribution of plants was influenced
by three factors including season, type of water bodies andpH of water.
Keywords: wetland plants, plant, diversity. Due Hue, Long An.
