Flower and floral buds on a leafless branch

Mountain ebony, one of the most beautiful trees when in flowering, is a native to the Indian subcontinent and China. However, it has been introduced in other parts of the world as well due to its usefulness in several ways. Also known as the orchid tree or camel’s foot tree, it is widely known as Kachnar in most parts of India. Botanically, it is known as Bauhinia variegata (generic name derived from the names of Swiss botanists Jean and Gaspard Bauhin brothers; the specific name refers to the variegation of the flowers) and belongs to the family Fabaceae (Leguminosae). In India, it is reported to occur throughout the country except in high-altitude areas in the Northwest Himalaya.

They have five petals and five fertile stamens. Fruit is a pod that measures up to 30 cm long and 3 cm broad. It contains 10-15 seeds in each pod.
