The difference between yellow acacia and yellow acacia

1. Difference of blades

There are 8-12 pairs of leaflets in Sophora japonica, which are opposite or nearly opposite, papery, oblong or oblong, with obtuse ends and awn tips. The midrib is concave above and obviously raised below. The yellow acacia has 7-9 pairs of leaflets, which are oblong or ovate, and the two are similar in size.

2. The difference between flowers

The yellow locust tree has a raceme inflorescence growing at the top, with a large and dense number of flowers, awl-shaped bracts, bell-shaped calyx, and a yellow, nearly round corolla. The yellow sophora also has a raceme inflorescence that grows in the leaf axils on the upper part of the branches. The bracts are ovate-oblong and the sepals are ovate. The flower colors of the two are almost the same. The petals are bright yellow to dark yellow, and ovate to obovate.
