The size of the mature tree is reported to be small to medium, attaining heights up to 20 to 30 m, and diameters of about 40 to 60 cm. Odor typical odor, bitter taste. It is considered to be moderately difficult to season Drying Defects: Aspidosperma species exudate a milk. Natural Habitat It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations.
Grain It has interlocked grain. Flooring 14 – Handbook of Hardwoods.
General Housing 10 – Silica in Timbers. The higher availability of nutrients at marocarpon moment of gall induction was demonstrated and seems to be important not only for the establishment of the galling insect but also for the responsiveness of the host plant tissues. In Peru cupping is reported.
Crossties 8 – Maderas latinoamericas. Vessels per mm2 10 to 20 abundant. The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality. Actual Dry Kiln Program http: Luster Luster is moderate to high. Moulding Molding operations are fair.
Boring Boring operations are reported to be fair. Assuming the morphological similarity between host leaves and intralaminar galls, a gradient from non-galled leaves towards galls should be generated, establishing a morpho-physiological continuum. Our objective was to analyze the nutritional status and the establishment of a physiological continuum between the galls and the non-galled leaves of A.

Careful drying is recommended. The period of leaf flushing coincided with the highest levels of nitrogen allocated to the new leaves, and to the lowest levels of carbohydrates.
Rays more than 10 per mm abundant. This first senescent leaves caused insect mortality. Parquet 15 – Empire Timbers. It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. The phenology, infestation of galls, and the carbohydrate and nitrogen contents were monthly evaluated in individuals, from September to September Furniture Cabinets 21 – Tropical timbers of the world.
