Botanical Description
Bauhinia variegata is a deciduous tree that typically grows up to 10-12 meters in height, though it can reach heights of up to 20 meters under favourable conditions. The tree is characterized by its distinctive bilobed (twin-lobed) leaves, which resemble the shape of a butterfly. Each leaf consists of two lobes joined together at the base, giving it a unique appearance.
The flowers of B. variegata are large, showy, and often bi-coloured, with shades of pink, purple, red, or white. They are borne in clusters and have five petals, with the uppermost petal modified into a prominent central boss known as the "standard." The flowers are rich in nectar and attract pollinators such as bees, butterflies, and birds. The fruits of B. variegata are elongated pods, often curved, and can reach lengths of up to 30 centimetres. When mature, the pods split open to reveal flat, brown seeds embedded in a fibrous pulp. The seeds are dispersed by wind or animals, aiding in the plant's reproduction and distribution.
Taxonomy and Distribution
Bauhinia variegata belongs to the genus Bauhinia, which comprises over 200 species of flowering plants distributed across tropical and subtropical regions worldwide. Within the Fabaceae family, B. variegata is classified under the subfamily Caesalpinioideae. The species has a wide distribution range, primarily in South Asia, but it is also found in Southeast Asia, China, and parts of Africa. It thrives in diverse habitats, including forests, grasslands, scrublands, and urban areas, and is often cultivated as an ornamental plant in gardens and parks.
Growth Habits and Ecological Requirements
Bauhinia variegata is adaptable to various soil types but prefers well-drained soils with moderate fertility. It grows best in full sunlight but can tolerate partial shade. The tree is drought-tolerant once established but benefits from regular watering during the growing season, especially in dry regions. In terms of ecological requirements, B. variegata is known to play a role in ecosystem restoration and soil conservation due to its nitrogen-fixing ability and extensive root system. It provides habitat and food for a variety of wildlife, including birds, insects, and mammals. [4-6]
