The genus name Bombax is likely derived from the Greek bombyx, referring to things of silk or cotton, and refers to the abundant, silk-like or cottony fibers in the fruits. The specific epithet or species name ceiba is a Spanish derivative of a Taino or other Arawakan (South American indigenous languages) name used for a group of large, tropical trees linked to Bombax, many of which produce kapok or silk-cotton in their fruits. It is often referred to as the ‘silent doctor’ for the host of medicinal benefits that it offers. Each part of the tree, including the bark, flowers and leaves have therapeutic uses. Herbal composition made from the bark of the tree, for example, is administered for the treatment of sexual and gastrointestinal disorders.
Red silk cotton tree is a medium to large, long-lived, briefly deciduous, fast-growing, tropical tree that grows up to 20-25 m tall and spreads 8-15 m wide. The plant is found growing in hot, humid, seasonally dry, mostly lowland, tropical moist, deciduous monsoon forests in river valleys, hillsides, road sides, forest and along open streams. The plant does best on deep sandy, well drained loams on alluvium near rivers and streams. It occasionally occurs on heavier but well drained soils on slopes. The plant has erect stem that develops buttresses when mature and an umbrella shaped crown.
The plant has impressive, straight, often stout trunk, 1-5 feet in diameter, often short and thick on cultivated specimens in open sites but a straight, symmetrical bole 50-125 feet to the first branch on forest specimens growing under favorable conditions; invariably buttressed at the base on large specimens, the buttresses extending up the trunk for 15-25 feet.
Bark is smooth and greenish gray on young trees, becoming rough, checked, with irregular vertical fissures and gray-white to silver-gray, greenish gray, or brown, typically with sharp, straight, stout, tan to brown, conical prickles to 0.5 inch long, these occasionally enclosed by expanding bark.
Leaves are palmately compound, about 24 inches long. Petiole is 4-8 inches long. Leaflets are about 3-7, digitately arranged, 3-10 × 0.6-3 inches, oblong to oblong lanceolate. Leaflet stalks are about 0.6-1.6 inches long, tip pointed, glabrous (without hairs or other coverings).
A Flower occurs solitary but densely placed near branch tips, conspicuous and very showy, 4-7 × 4-7 inches. Calyx is cup-shaped, 3-5-lobed, 0.8-1 inch long, outer or lower surface glabrous, inner or upper surface densely covered with yellowish silky hairs. Petals are 3.1-4 × 1.4-2.2 inches, recurved, dull to bright red, less frequently orange-red, orange, or rarely white, thick, fleshy, waxy, satiny, densely covered with short, soft hairs. Stamens are yellowish but red tinged toward the tips. Anthers is black, in 2 whorls, outer whorl divided into 5 bundles of 9-20 each, inner whorl of 10-15 surrounding the style, less than half as long but reaching rim of recurved petals, about three-quarters as long as style. Flowering normally takes place from January to March.
Fertile flowers are followed by capsule, 4-6 × 1.8-2 inches, ovoid, pointed, longitudinally ribbed, densely covered with grayish white hairs, splitting open along 5 seams to reveal white, cottony, silky material. They are initially green when young turning to brown as they matures. Seeds are smooth, black or grey surrounded in long white wool, which are irregular obovoid in shape, smooth and oily with dense silky hair.
Fruits are full of cotton-like fibrous stuff. It is for the fiber that villagers gather the semul fruit and extract the cotton substance called “kopak”. This substance is used for filling economically priced pillows, quilts, sofas etc. The fruit is cooked and eaten and also pickled. Its wood, when sawn fresh, is white in color. However, with exposure and passage of time it grows darkish gray. It is as light as 10 to 12 kg, per cubic foot. It is easy to work but not durable anywhere other than under water. So it is popular for construction work, but is very good and prized for manufacture of plywood, match boxes and sticks, scabbards, patterns, mould, etc. Also for making canoes and light duty boats and or other structures required under water. Bombax species are used as food plants by the larvae of some Lepidoptera species including the leaf-miner Bucculatrix crateracma which feeds exclusively on Bombax ceiba.
