The umbrella thorn, (Vachellia planifrons), is a species of Vachellia of the family Fabaceae. It is native to India and Sri Lanka.
Vachellia planifrons is a medium-sized tree that generally attains a height of 5âÂÂ15 m (16âÂÂ49 ft). The trunk , typically measures 30âÂÂ60 cm (12âÂÂ24 in) in diameter. Its bark is grey to brown in coloration and characteristically rough, often developing deep fissures that provide shelter for insects and nesting opportunities for birds. The branches are adorned with large thorns that act as a defense against herbivores. This tree also often produces a distinct flat-topped umbrella-shaped canopy.
The foliage consists of small, bipinnate leaves approximately 2âÂÂ5 cm long. Each leaf is divided into numerous paired leaflets, giving it a fine, feathery appearance. The leaves are bright green and adapted to function efficiently under dry climatic conditions.
Flowering occurs seasonally, usually in late spring to early summer. During this period, the tree bears clusters of spherical, white blossoms that are notably fragrant.
