The Netherlands has introduced a €49 monthly ticket for unlimited nationwide train travel—a bold political response to soaring energy costs. When prices at the pump rise, you can either double down on car dependency, or give people attractive alternatives. The Dutch are (again) choosing the latter.

One diagram illustrates the Widened Pipe Model, showing a constant number of xylem conduits along the stem and progressive conduit widening from the tip toward the base. A second diagram illustrates a furcation-based model, where conduit number increases toward the tip through repeated branching. A schematic of a long, unbranched stem with leaves concentrated near the tip shows the locations of the basal and apical segments that were sampled to test whether conduit number increases toward the stem apex.
