The period of leaf flushing coincided with the highest levels of nitrogen allocated to the new leaves, and to the lowest levels of carbohydrates. Sawing Cutting resistance is generally low. In Axial parenchyma absent or extremely rare, non visible with magnifying glass 8x.


Steps 17 – Tree Conservation Database. Vessel-ray pits similar to intervessel pits in size and shape.

It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. Minor warping and checking are reported. Vessels per mm2 10 to 20 abundant. Natural Habitat It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. Odor aspidlsperma odor, bitter taste.

Rays more than 10 per mm abundant. Grain It has interlocked grain. Moulding Molding operations are fair. The nutrients were previously consumed by the growing leaves, by the time of gall induction.

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. Planing This species is easy to plane.

General Housing 10 – Silica in Timbers. Fibers with distinctly bordered pits. Aspidosperma species exudate a milk. The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality.

The boles are often straight and cylindrical, covered with a typically ridged bark. 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. Tangential diameter of vessel lumina micras or less very small. This first senescent leaves caused insect mortality.

Luster Luster is moderate to high. Amcrocarpon 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.
