Odor typical odor, bitter taste. Furniture Cabinets 21 – Tropical timbers of the world. Botanical Description 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.

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. Nailing Nailing properties are poor. Boring Boring operations are reported to be fair. Rays more than 10 per mm abundant. This first senescent leaves caused insect mortality. The higher availability of nutrients at the 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.

Heavy Packing 47 – Arvores Brasileiras. General Housing 10 – Silica in Timbers. Flooring 14 – Handbook of Hardwoods. Scientific Name Aspidosperma macrocarpon Mart. Steps 17 – Tree Conservation Database. Scientific Name Synonyms Macaglia macrocarpa Mart. The phenology, infestation of galls, aspidosperrma the carbohydrate and nitrogen contents were monthly evaluated in individuals, from September to September Fibers with distinctly bordered pits.

Natural Habitat It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their macrofarpon sink functionality. Aspidosperma species exudate a milk.

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. The joint interpretation of phenology and nutritional metabolism provides important macricarpon on plant tissues reactivity and the period of gall induction. Sawing Cutting resistance macrocarpln generally low. The nutrients were previously consumed by the growing leaves, by the time of gall induction.


Planing This species is easy to plane. The leaves were infested in October, galls developed along the year, and gall senescence took place from March to September, together with host leaves.

It is considered to be moderately difficult to season Drying Defects: Vessels per mm2 10 to 20 abundant.

Careful drying is recommended. The boles are often straight and cylindrical, covered with a typically ridged bark.
