This beautiful has started flowering in Kolkata, though the pictures attached are of 2007.
Bombax ceiba, like other tree from genus
Bombax, is commonly known as
cotton tree or
tree cotton. The tropical tree is with straight tall trunk and its leaves are
deciduous in winter. Red flowers with 5 petals are born in the spring before green leaves. Small husks raped contain fibres like cotton. Its trunk bears spikes to deter attacks by animals. Although its trunk looks good for timber, its wood is too soft for use.
The
cotton in the husks were used a substitute of
cotton. Its flower was a common ingredient in
Chinese herb tea.
The Sanskrit name for this tree is Salmali. In the Rigveda, the chariot is made of Salmali (RV 10.85.20) and other woods.
Folk knowledge in Hong Kong states that soon after the tree blooms, the weather will get hotter.
Bombax species are among the largest
trees in their regions, reaching 30 to 40 metres in height and up to 3 metres trunk diameter. The
leaves are compound with entire margins and
deciduous, being shed in the dry-season. They measure 30 to 50 cm across and are palmate in shape with 5 to 9
leaflets. The
calyx is deciduous, meaning it does not persist on the fruits. They bear 5 to 10 cm long red
flowers between January and March while the tree is still leafless. The
stamens are present in bundles in two whorls, while the staminal column lacks lobes. The
ovary matures into a husk containing seeds covered by a fibre similar to that of the
kapok (
Ceiba pentandra) and to
cotton, though with shorter
fibres than cotton, that does not lend itself to spinning, making it unusable as a textile product.
