An unique sclero-microphyllous evergreen broad-leaved community in the valley of Lancang (upper Mekong) River was recorded using the methodology of Braun-Blanquet’ s releve. The plant community was nominated by Association Olea ferruginea, Pistacia weinmannifolia. It was mainly happened at altitude 1 300 m to 1 900 m above sea level along the river banks. Its physiognomy, life/growth form, and floristic components were summarized, depending field-collected releves. The results indicated community structure was relatively simple, with average species number of 18; Phanerophytes were the most common life form, and growth form was dominated by herbs; There were 116 vascular species, 39 families, and 84 genera in 15 releves; Its flora had a tropical characteristics at family and genus level. This association was supposed to be a relic vegetation of paleomediterrean subtropical vegetation which is characterized by small and scelrophyllous leaves. With growing human impact of dams construction, this plant community type which remains and evolves in a narrow valley were worth of protection and further research.
