The wood anatomy of ring-porous trees presents difficulties of description and measurement. Information regarding the distribution of vessel diameters within the yearly growth increment may be of use of interpreting wood anatomy and function. Two distributional patterns can be recognized in the trunk xylem of the five ring-porous species investigated. The following terms are proposed: graduated-unimodal, to refer to ring-porous woods with one population of vessels, and graduated-bimodal, to refer to woods with two distinct peaks in vessel frequency.
