Cotton tree or Semal

Description:

Bombax ceiba, like other trees of the genus Bombax, is commonly known as cotton tree. This tropical tree has a straight tall trunk and its leaves are deciduous in winter. Red flowers with 5 petals appear in the spring before the new foliage. It produces a capsule which, when ripe, contains white fibres like cotton. Its trunk bears spikes to deter attacks by animals. Although its stout trunk suggests that it is useful for timber, its wood is too soft to be very useful. Bombax ceiba grows to an average of 20 meters, with old trees up to 60 meters in wet tropical weather. The trunk and limb bear numerous conical spines particularly when young, but get eroded when older. The leaves are palmate with about 6 leaflets radiating from a central point, an average of 7~10 centimeters wide, 13~15 centimeters in length. The leaf's long flexible petiole is up to 20 cm long. Cup-shaped Flowers solitary or clustered, axillary or sub-terminal, fascicles at or near the ends of the branches, when the tree is bare of leaves, an average of 7~11 centimeters wide, 14 centimeters in width, petels up to 12 centimeters in length, Calyx is cup-shaped usually 3 lobed, an average of 3~5 centimeters in diameter. Staminal tube is short, more than 60 in 5 bundles. Stigma is light red, up to nine centimeters in length, Ovary is pink, 1.5~ 2 centimeters in length, with the skin of the Ovary covered in white silky hair at 1mm long. Seeds are numerous, long, ovoid, black or gray in colour and packed in white cotton. The fruit, which reaches an average of 13 centimeters in length, is light-green in color in immature fruits, brown in mature fruits.

Habitat:

The tree is widely planted in Malay, Indonesia, south China, Hong Kong and Taiwan

Notes:

This tree is commonly known as Semal (Hindi:सेमल) in India. It is widely planted in parks and on roadsides there because of its beautiful red flowers. The cotton fibers of this tree can be seen floating in the wind around the time of early May. The flowers are very attractive to local wildlife
