Acacia polyyriifolia is a fast-growing small tree in the Fabaceae family, belonging to the genus Acacia. It can grow up to 6 meters tall, with a crown that can extend up to 3 meters wide, and a beautiful and handsome tree shape. When it was young, its leaves were pinnate compound leaves, but as adults, the leaves degenerated until they disappeared, while the silver petiole gradually widened, resembling a single leaf, replacing the original function of the leaves.
