I saw a tree when I was traveling in Guilin. The leaves are like half-cut apples. The diameter of the leaves is about 10-18cm. It is very beautiful. What kind of tree is it? Thanks

I think you are talking about sheep's hoof beetles, right?

Ocean's hoof beetle is a leguminous tree or upright shrub plant, 7-10 meters high; the bark is thick, nearly smooth, gray to dark brown. It is very similar to Hong Kong's red flower beetle and can easily be confused. It belongs to the Fabaceae family. This species has light red flowers and forms pods after flowering, which is different from the latter which has purple-red flowers and does not form pods after flowering. This species is a good landscaping tree species and is often planted as a street tree along the roadside. The medicinal material Bauhinia variegata L. is a plant of the same genus, also known as Bauhinia variegata L., and its roots, bark, leaves and flowers are used as medicine. From the "Compilation of National Traditional Chinese Medicines", roots and bark can be harvested throughout the year, while leaves and flowers can be harvested in summer and dried in the sun. It has the effects of strengthening the spleen, drying dampness, reducing inflammation and stopping bleeding. In addition, it also has its cultural connotation. Famous literary artists Xi Murong and Qin Mu made fascinating and lyrical descriptions in their prose poems.
