Missouri Botanical Garden states that Syringa reticulata is the Chinese Tree Lilac, while S. reticulata ssp. reticulata is the Japanese Tree Lilac. In the NGA Plants Database, Syringa reticulata is given the common name of Japanese Lilac, which is a conflict.

GRIN calls S. reticulata simply Tree Lilac, but like the Missouri Botanical Gardens, they also call S. reticulata ssp. reticulata Japanese Tree Lilac.
Charles Sargent's S. japonica = S. reticulata ssp. reticulata.
Meanwhile, I'm not sure I've ever even seen a lilac of any kind...?
