The genus  Clematis  contains many well-known large flowered cultivars, as well as lesser-known nonvining species. Intersimple sequence repeat (ISSR) primers were used to fingerprint 32 vining cultivars and five nonvining species ( C. fruiticosa, C. integrifolia, C. heracleifolia, C. hexapetala,  and  C. recta ) for use in assessing genetic relationships and cultivar identification. Four ISSR primers yielded a total of 44 bands in the vining accessions, of which 36 (86%) were polymorphic. The average polymorphism levels were 83% for the cultivars and 94% for the nonvining species. All 32 vining cultivars were distinguished with the use of two ISSR primers, and the five nonvining  Clematis  species were differentiated with three ISSR primers. A similarity matrix of the cultivars showed low similarity levels between the samples, with an average similarity of 0.28. A UPGMA-derived dendrogram showed no strong groupings among any of the samples. Two cultivars with known parentage,  Clematis viticella  L. `Betty Corning' and `Sylvia Denny', grouped with one reported parent but not the other, suggesting they are more similar to one parent. `Multi-blue', a sport reportedly arising from `The President' did not segregate near `The President'.
