Oroxylum indicum is a species of flowering plant belonging to the monotypic genus Oroxylum and the family Bignoniaceae, and is commonly called Indian trumpet tree, oroxylum, Indian trumpet flower, broken bones, Indian caper, scythe tree or tree of Damocles. It can reach a height of 18 metres (59 ft). Various segments of the tree are used in traditional medicine, where it is known as Shyonaka or Sona Patha. [1]wikipedia

The large leaf stalks wither and fall off the tree and collect near the base of the trunk, appearing to look like a pile of broken limb bones. The pinnate leaves are approximately 1 metre (3.3 ft) in length and comparably wide, borne on petioles or stalks up to 2 metres (6.6 ft) in length, making this the largest of all dicot tree leaves, which are quadripinnate (leaflets display four orders of branching). [2]wikipedia

The tree is a night-bloomer and flowers are adapted to natural pollination by bats. They form enormous seed pods – the fruits – are up to 1.5 meters (4.9 ft) long that hang down from bare branches, resembling swords. The long fruits curve downward and resemble the wings of a large bird or dangling sickles or swords in the night, giving the name “tree of Damocles”. The seeds are round with papery wings. [3]wikipedia

Oroxylum indicum is native to the Indian subcontinent, the Himalayan foothills with a part extending to Bhutan and southern China, Indochina and the Malesia regions. In Vietnam, the tree is called núc nác (sometimes sò do), and specimens can be found in Cat Tien National Park. [4]wikipedia
