 Fifteen characters were measured in 11 populations of Gnetum parvifolium in Fujian Province, including 1139 leaves from 116 plants. The diversity index is 19281 at species level and 17573 at population level. 9114% of all genetic variation is distributed within populations. UPGMA cluster analysis and Mantel test also support that there is a positive correlation (r=06216, P=00020<0005) between genetic distance and geographic distance. The population differentiation conforms to the isolationbydistance pattern.

Key words: Gnetum parvifolium, Population, Genetic variation, Morphology of leave
