Fig. 7

Z. noltii. Plant clonal topology of Z. noltii plants using a the branching pattern recorded in this paper (i.e. “natural branching”) and a branching angle of 90^°, b the branching pattern recorded in this paper and a branching angle of 45^°, c the opposite branching pattern recorded in this paper and a branching angle of 90^°, d the opposite branching pattern recorded in this paper and a branching angle of 45^°. All figures are constructed using 11 nodes and branches from the second one. The numbers indicate the reduction (negative values) or increment (positive values) in the area occupied in comparison with (a). The inset figures indicate the “natural branching” (a, b) and “opposite branching” (c, d) pattern. See text for further information
