Syringa reticulata 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 leaves are
1104 Syringa of 0.34 and an inclination of 6° with respect to the ecliptic. For a main-belt asteroid, it has a rather high eccentricity. The body's observation arc begins at Heidelberg on 1 January 1929, three weeks after its official discovery observation. In the SMASS classification, "Syringa" is a Xk-subtype that transitions between the X- and the dark and uncommon K-type asteroids. It has also been characterized as an X-type by Pan-STARRS photometric survey, and as a primitive P-type asteroid by the Wide-field Infrared Survey Explorer (WISE). In February 2006, a rotational lightcurve of "Syringa" was obtained from photometric observations at the
