A phytosociological analysis of low-canopy forest near the Alas and Ketambe rivers in Ketambe, G. Leuser National Park, Sumatra was carried out using a quadrat method. A complete enumeration in 1.6 ha plot revealed 127 species, 86 genera and 50 families of trees with DBH 10 cm. The density was 466 trees/ha with the total basal area of 41.55 m2/ha. Euphorbiaceae was the most common family which comprises 15 species with a density of 135 trees/ha (28.4 percent). Five of the important species with importance values greater than 10 were recognized. The most dominant was Ficus sp. (IV = 20.23) followed by Dendrocnide sinuata (IV = 18.01). A dipterocarp species, Parashorea lucida, was recorded as the third most dominant species with importance value of 17.28. The differences with the other nearby forest are discussed.
