Oroxylum indicum is a species of flowering plant belonging to the monotypic genus Oroxylum and the family Bignoniaceae, are commonly called midnight horror,oroxylum,Indian trumpet flower,broken bones,Indian caper, or tree of Damocles. It can reach a height of 18 metres (59 ft). Various segments of the tree are used in traditional medicine.
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).
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 metres (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.
O. 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 đo), and specimens can be found in Cat Tien National Park.
It is visible in the forest biome of Manas National Park in Assam, India. It is found, raised and planted in large number in the forest areas of the Banswara district in the state of Rajasthan in India. It is reported in the list of rare, endangered and threatened plants of Kerala (South India). It is also found in Sri Lanka.
