Description Of The Tree
Botanical Description
It is reported to attain heights of up to 40 m, with cylindrical and straight boles up to 20 m long. The diameter is commonly 80 cm in diameter. The tree is covered with prickles, and it usually develops irregular stems.
Natural Habitat
Bombacopsis quinata is found in tropical rain forests, in well drained soils, on the upper slopes of hills and ridges. Burning, overexploitation of the timber and increasing settlement and conversion of the habitat for agriculture are causing population a
Natural Distribution
This species is found from southern Honduras to northern Colombia and Venezuela, it occurs in the more open forests of Nicaragua, Costa Rica, and Panama.
Plantations Available?
The species is grown in small-scale species trials in Kenya and the Solomon Islands.

Simple perforation plates. Vessel-ray pits larger than the intervessel pits Occasionally axial parenchyma in marginal or in seemingly marginal bands. Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Axial parenchyma storied. Prismatic crystals in non-chambered axial parenchyma cells. Occasionally prismatic crystals 4 to 10 rays per mm (medium). Occasionally rays storied. Larger rays more than 4 seriate. Occasionally prismatic crystals in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with one row of upright and/or squa Septate fibers present. Fibers with simple to minutely bordered pits.
