The true Clematis ochotensis is still unknown to us from our 

 Corean territories. It grows in Saghalien, Yeso and Hondo varying 

 slightly in their natives. There is a distinct variety in North-Hondo (like 

 Mt, Genjusan, Mt. lidesan, Mt. Hakkodasan and Mt. Hayachinesan) 

 which has always tcrnate leaves. The segments are trisect or bisect 

 and always broad. Its name is Clematis ochotensis, Poiret var. 

 ternata, Nakai.
