What is the difference between Chinese ash (Fraxinus hupehensis) and Chinese privet (Ligustrum quihoui)?
I. Differences in the trunk
Chinese ash is a large deciduous tree, reaching a height of 19 m and a diameter of about 1.5 m, with bark that is dark gray on the surface. Mature trunks have vertical cracks.
Chinese privet is a deciduous shrub, 1 to 3 m tall, much shorter than the former.
II. Differences in the leaves
Chinese ash leaves are lanceolate to ovate-lanceolate, about 1.7 to 5 cm long and 0.6 to 1.8 cm wide, with small serrations along the leaf edges and no small hairs on the surface. There are relatively many lateral veins, 6 to 7 pairs, and the petiole is 3 cm long.
Chinese privet leaves vary noticeably in shape and size; oblong-elliptic, elliptic, and obovate-oblong are all possible, about 1 to 4 cm long and about 0.5 to 2 cm wide, with the leaf edges rolled inward. There are 2 to 6 pairs of lateral veins, which look inconspicuous, and the petiole is about 5 mm long.
