The results show that the morphological variation of 11 morphological traits, including length of beak, length of fruit, w idth of fruit, shape of fruit, length of achene, w idth of achene, shape of achene, length of bristle, the length of bristle of head, the distance between ribs and the distance between bristles, existed both w ithin p lant and amang p lants, and the degree of variation within p lantwere lesser than amang p lants. There is obvious corre2 lation in indices of the fruits and the achene sizes( p < 0. 01). However, the shape of achene and the distance between ribs are negatively correlated ( r = - 0. 297 3 3, p < 0. 01), which means width of achene increases with the distance between ribs. It was concluded that the shape of the fruits and achenes could be used for species classification; and those characteristics w ith greater p lasticity were less useful in distinguishing the sibling species w ith sympatric distribution. This result can be referred to classify of other species in Ca lligonum.
