Figure S1. Representative freehand transverse sections through a P. aquilinum frond at 20 cm intervals. Bar = 1 mm.

Figure S2. Representative freehand transverse sections through a W. fimbriata frond at 20 cm intervals. Bar = 1 mm.

Figure S3. High-resolution computed tomography images of P. aquilinum (a,c) and W. fimbriata. (b,d). Each column shows the 1.5 cm long frond segments rotated in 45° increments over 180°, revealing primary xylem bundles (blue) and the surrounding tissue (green). The upper and middle rachis of P. aquilinum (a and c, respectively) consist of many more xylem bundles with multiple connections, typically located in the axis junctions. The upper and middle rachis of W. fimbriata (b and d, respectively) consist of two and five xylem bundles, respectively, with few connections.

Figure S4. Conduit diameter distributions in P. aquilinum (a–c) and W. fimbriata (d–f) at upper rachis (a,d), the middle rachis (b,e) and the lower rachis (c,f). Bars – ±SE, n = 4. Arrows show bins with low frequency.

Movie S1. Three-dimensional HRCT volume renderings of the xylem network of 1.5 cm of lower rachis tissue in P. aquilinum and W. fimbriata fronds. This movie shows the interconnected P. aquilinum xylem network and the sectored W. fimbriata xylem network with a single connection between two small bundles.

Movie S2. Three-dimensional HRCT volume renderings of the xylem network of 1.5 cm of upper rachis tissue in P. aquilinum and W. fimbriata fronds. This movie shows the interconnected P. aquilinum xylem network and the sectored W. fimbriata xylem network. In W. fimbriata, the bifurcations of the two large bundles that supply the pinnae are visible.
