During secondary growth, cells of medullary rays, in a line (as seen in section; in three dimensions, it is a sheet) between neighbouring vascular bundles, become meristematic and form new interfascicular cambium (between vascular bundles). The molecular mechanisms of the plant secondary growth, which gives rise to girth expansion in trees, have been little understood.
