Millingtonia hortensis, Tree Jasmine or Indian Cork Tree, the sole species in the genus Millingtonia, is a tree native to South Asia & South East Asia. It is known as Akash Mallige in Kannada, Akash Malli or Mara Malli in Tamil, Kavuki in Telugu, Pip in Thai: ปีบ and Mini Chameli in Hindi, Akash Mallee in Oriya.
In the name Millingtonia hortensis, Millingtonia is named for Sir Thomas Millington who was an inspiration to Carl Linnaeus the Younger who first described the genus. The specific epithet 'hortensia' derives from 'hortensis' and 'hortus' which in Latin is related to garden. In its synonym, Bignonia suberosa, 'suberosa' derives from 'suberos' which means 'corky' in Latin.
The tree grows to height of between 18 to 25 metres and has a spread of 7 to 11 metres. It reaches maturity between 6 to 8 years of age and lives for up to 40 years. It is a versatile tree which can grow in various soil types and climates with a preference for moist climates.
The tree is evergreen and has an elongated pyramidal stem. The soft, yellowish-white wood is brittle and can break under strong gusts of wind.
The tree flowers twice a year from April till the rains and from October to December. The white flowers come as large panicles which emit a pleasant fragrance. They are bisexual and zygomorphic. The bell-shaped sepals of the flower have five small lobes. The flower has four stamens with parallel anthers unlike in most other plants of this family where the anthers are divergent. The corolla is a long tube with five lobes.
Fruit and seed
The fruit is a smooth flat capsule and is partitioned into two. It contains broad-winged seeds. The fruits are fed on by birds which aid in seed dispersal. In cultivation, the viability of seeds is low unless they are sown immediately after the fruit ripens, so the plant is generally propagated through cuttings.
The tree is considered ornamental and the pleasant fragrance of the flowers renders it ideal as a garden tree. The wood is also used as timber and the bark is used as an inferior substitute for cork. The leaves are also used as a cheap substitute for tobacco in cigarettes.
