Longitudinal internode (scape) of culm. a Transverse view with medullary and peripheral veins. Bar is 1.0 mm. b Delaunay triangulation of vein centers with no intersecting radii. Number of radii around each center is by definition the number of nearest neighbors. c Two small and one large peripheral veins, one large medullary vein and three sclerenchyma bundles (above the peripheral vein). Bar is 150 µm. d Medullary veins with cross, commissural veins. Bar is 380 mm. e Peripheral veins with no cross veins. Bar is 300 µm. f Medullary veins at 7th bract internode. Veins are internally and externally (R = 0.95, random) disorganized. Bar is 170 µm
