The concept of cambium,procambium→cambium continuum are comprehensively reviewed and discussed. Metacambium is proposed as an intermediate state between procambium and cambium. Recent attempts to define the cambial state both in terms of the meristem and its derivatives are discussed.

Highlights in the early history of the International Association of Wood Anatomists,iation until a formal Council, as provided in the constitution, could be elected. To this end Record invited a group of internationally known wood anatomists to join the Association as founder or charter members. Thirty-six persons from 14 countries signified their intent to associate with the new s

An anatomical explanation for visco-elastic and mechano-sorptive creep in wood, and effects of loadcrystalline and non-crystalline components of the cell wall. An added influence of moisture reduction or moisture cycling is similarly explicable. Furthermore, it is shown that effects so deduced are fully compatible with the extensive experimental data in the literature..Experimental data show that

Functional xylem anatomy of angiosperm trees, wood in axial direction with relative ease. This remarkable combination of efficiency and safety is only possible because of the intricate three-dimensional structure of wood. Small-diameter and short vessels are safer water conductors, wide and long ones are more efficient. This paper describes ho

This process removes the non-cellulosic matrix components from unlignified walls leaving a cellulose microfibrillar web or net. Where these webs traverse small openings as in tracheid and vessel element pit membranes, they usually survive intact. Where they traverse larger openings as in v

The concept of cambium,, a generalised idea of what cambium should be. As a concept, the cambium must be treated either by developmental states or in some specific way in which it is manifested. It is noted that procambium is initiated in the embryo and perpetuated in the apical shoot. The residual meristem is discussed a

An anatomical explanation for visco-elastic and mechano-sorptive creep in wood, and effects of loadwith time (creep). With any particular intensity of stress, it is well documented that the rate of creep varies significantly, according to whether the stress mode is in compression, bending, tension or shear. Additionally, it has been shown that the amount of creep tends to be considerably greater,
