In the mitotically active vascular cambium of conifers and broadleaved trees there is tension across the radial middle lamellae. This tension seems to be important for intrusive growth of fusiform cells. In the vascular cambium of Fraxinus and Robinia there is tension across the tangential middle lamellae also, which makes possible the increase in diameter of differentiating vessel members.
