Nyctanthes arbor-tristis

Fruit in Bardhaman, West Bengal, India

The tree is called the "tree of sorrow" because the foliage becomes droopy as blooming flowers fall off during early morning.[9] The Latin specific epithet arbor-tristis means "sad tree".[9] In India, Nyctanthes arbor-tristis is known as pārijāta (पारिजात), harsinghar, sephalika, pavalamallikai, manjapumaram, mannappumaram and siharu.[10] In Malaysia it is known as seri gading and in China it is referred to as nai hua or hung mo li.[10]

Nyctanthes arbor-tristis is a shrub or a small tree growing to 10 m (33 ft) tall, with flaky grey bark. The leaves are opposite, simple, 6–12 cm (2.4–4.7 in) long and 2–6.5 cm (0.79–2.56 in) broad, with an entire margin. The flowers are fragrant, with a five- to eight-lobed white corolla with an orange-red centre; they are produced in clusters of two to seven together, with individual flowers opening at dusk and finishing at dawn. The fruit is a bilobed, flat brown heart-shaped to round capsule 2 cm (0.79 in) diameter, each lobe containing a single seed.[4][5]

N. arbor-tristis is native to Indo-China, Himalaya and Sumatera to Jawa.[11] It grows in dry deciduous forests and hillsides.[12]

The leaves have been used in Ayurvedic medicine and Homoeopathy for sciatica, arthritis, and fevers, and as a laxative.[13] An orange dye from the corolla, nyctanthin, is used to dye silk.[14] In India, flowers are used to make garlands and used for worship.[9]

The flower of Nyctanthes arbor-tristis is the official state flower of West Bengal and is called shiuli or shefali.[14]

The native people of Tripura use the plant to help predict weather and rainfall.[15]

Krishna Uproots the Parijata Tree, manuscript from a Bhagavata Purana.

The parijata is a divine tree featured in Hindu mythology.[16] The Mahabharata and the Puranas describe the parijata tree, as one of five trees, to have emerged during the legend of the Samudra Manthana.[17] Krishna is described to have battled with Indra to uproot the parijata from his capital of Amaravati and plant it in his own city of Dvaraka.[16] In regional tradition, Satyabhama grew aggrieved when Krishna offered his chief consort Rukmini a parijata flower. To placate her envy, Krishna confronted Indra and had the parijata tree planted near Satyabhama's door. Despite having the tree planted near her dwelling, the flowers of the tree fell in the adjacent backyard of Rukmini, the favourite wife of Krishna, because of her superior devotion and humility.[18][19]

The tree is the subject of a work named Parijatapaharanamu in Telugu literature, written by Nandi Thimmana, the court-poet of Krishnadevaraya.[16] The poet Kalidasa sings about the flower in his Sanskrit poem Ritu samhara.[9]
