Syringa reticulata North America. Syringa reticulata Syringa reticulata (Japanese tree lilac; ; ) is a species of Lilac, native to eastern Asia: in northern Japan (mainly Hokkaidō), northern China (Gansu, Hebei, Heilongjiang, Henan, Jilin, Liaoning, Nei Mongol, Ningxia, Shaanxi, Shanxi, Sichuan), Korea, and far southeastern Russia (Primorye). "Syringa reticulata" is a deciduous small tree growing to a height of 39' (12 m), rarely to 49' (15 m), with a trunk up to 11.8" (30 cm), rarely 15.7" (40 cm) diameter; it is the largest species of lilac, and the only one that regularly makes a small tree rather than a shrub. The
1104 Syringa Calvin–Rehoboth Observatory in New Mexico, United States. Lightcurve analysis gave a well-defined rotation period of 5.1547 hours with a brightness amplitude of 0.27 magnitude (). According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, "Syringa" measures between 19.711 and 24.30 kilometers in diameter and its surface has a low albedo between 0.031 and 0.045. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0434 and a diameter of 22.13 kilometers based on an absolute magnitude of 12.3. This minor planet was named after the genus
