Description Of The Tree
Botanical Description
The trees are reported to reach heights of 30 to 40 m, with diameters ranging from 50 to 80 cm. They develop straight and cylindrical boles, up to 15 m long. Lengths of 20 m are also possible.
Natural Habitat
Carapa procera is often a dominant species, which prefers humid areas. It can be found on hills or close to rivers.
Natural Distribution
Carapa procera has a wide growth range in tropical America and it is also found in West Africa, although the African trees do not reach the same dimensions as the American ones. In tropical America it is reported to occur from Costa Rica and Panama south
Wood Identification
Anatomic Description Of Wood
Occasionally tangential diameter of vessel lumina 200 micras or more. Red-colored deposits in heartwood vessels. Vessels per mm2 6 to 10 (medium). Intervessel pits small, 7 micras or less. Occasionally axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Occasionally axial parenchyma in marginal or in seemingly marginal bands. Occasionally paratracheal axial parenchyma scanty and/or vasicentric. Paratracheal axial 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Occasionally prismatic crystals in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Septate fibers present.
