Taxonomic notes: Based on the shape of fruits or the degree of development of ridges on fruits, several names were proposed such as T. ovalis, T. megaphylla Nakai, or T. simicostata Nakai (oval), but these traits as diagnostic characters of species were variable according to the maturation period. All of these taxa were synonymized as T. mandshurica.
