(A) Narrowly sagittate leaf (0.17). (B) Sagittate leaf (0.30). (C) Sagittate leaf (0.39). (D) Broadly sagittate leaf (0.45). (E) Hastate leaf. The middle lobe and lateral lobes are indicated by numbers 1 and 2, respectively. Values in brackets are the lateral lobe width:length ratios of the arrow-shaped leaves.

Population structure of 111 Sagittaria trifolia accessions generated using ADMIXTURE.
Each color represents one population. The vertical bars represent individual accessions. The ratio of each colored component in each vertical bar represents the membership probability of accessions belonging to different populations.

(A) Phylogenetic analysis of 111 S. trifolia accessions. Group I-1 accessions are in blue, Group I-2 accessions are in light blue, and Group II accessions are in green. (B) PCA plots of the first two components of the 111 S. trifolia accessions. The subpopulations defined by the PCA include Pop 1.1 (Group I-1), Pop 1.2 (Group I-2), and Pop 2 (Group II).
