Description Of The Tree
Botanical Description
It is a dominant tree, it attains heights from 30 to 40 m, with a diameter at breast height between 60 to 80 cm over the buttresses. It is reported to present a fluted bole, with well developed buttresses up to 6 m tall.
Natural Habitat
Minquartia guianensis prefers low lands in the primary forests. It thrives in very humid habitats.
Natural Distribution
It can be found from Nicaragua to Bolivia and Peru. It is also found in the Guyanas and Brazil.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 100 micras or less. Tyloses common. Occasionally vessels per mm2 more than 20. Scalariform perforation plates with 5 to 15 bars. Multiple perf Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Occasionally prismatic crystals in non-chambered axial parenchyma cells. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Over 9 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays commonly 2 seriate. Prismatic crystals in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Fibers with simple to minutely bordered pits.
