On the Cover: This cross-section of a laurel (Laurus nobilis) stem was stained with Fast Green by applying the dye to the exposed phloem of an intact stem. The dye migrated into the wood within minutes. The section shows solitary and grouped vessels closely associated with paratracheal (vasicentric) parenchyma and uni- to triseriate rays. The rapid movement of the dye suggests that the rays are a suitable route for rapid radial transport of water and solutes from the phloem to the xylem. We believe that such rapid transport contributes to the refilling of cavitated xylem conduits, as documented in Tyree et al. (pp. 11-21). (Photograph was taken by Maria A. Lo Gullo.)
