The cambium has been variously defined as follows: "The actively
dividing layer of cells that lies between, and gives rise to,
secondary xylem and phloem (vascular cambium)" (IAWA 1964); "A
meristem with products of periclinal divisions commonly contributed
in two directions and arranged in radial files. Term pre ferably
applied only to the two lateral meristems, the vascular cambium and
cork cambium, or phellogen" (Esau 1977); and, "Lateral meristem in
vascular plants which produces secondary xylem, secondary phloem,
and parenchyma, usually in radial rows; it consists of one layer of
initials and their undifferentiated deriva tives" (Little and Jones
1980). Clearly, the cambium is a diverse and extensive meristem,
and no one defini tion will encompass all manifestations of what
anatomists consider cambium. Its diversity and extent are further
exemplified by a single plant, such as a temperate zone tree, in
which procambium is initiated in the embryo and perpetuated
throughout every lateral, primary meristem before giving rise to
cambium in the secondary body. The cambium thereafter performs its
meristematic task of producing daughter cells that differentiate to
specialized tissue systems. The cam bium, however, does not remain
static. Its derivatives vary either in form, or TImc tion, or rate
of production at different positions on the tree, with age of the
tree, and with season of the year. Moreover, the cambium responds
both to internal sig nals and to external stimuli such as
environment or wounding."
