Fig 1.
Mature plant (left), male flower bud (middle), and leaf lamina basis (right) of M. splendida (A) and M. viridis (B).
The difference in flower bract color is used as the main morphological discriminant between these species (red in M. splendida and pink in M. viridis).
Fig 2.
Map of the nine sampling locations of the M. splendida and M. viridis accessions in Viet Nam.
Labels correspond to the ID of each sampling location and pie charts indicate the proportion of M. splendida (red), M. viridis (pink), and unknown individuals (grey) per population. All populations were located close to the Chay river and Red river (blue lines) in the northern part of the country (blue dots in black circle in inset).

Fig 3.
Plot of the first two principal coordinates (PC) that were constructed based on the haplotype variation across the 121 Musa individuals.
The first and second coordinate explained 25.2% and 7.7% of the total variation in the dataset, respectively. Individuals were colored based on population ID (left) and taxon ID (right).

Barplot showing the membership probabilities of each individual to one of the four subpopulations (k = 4).
Numbers below the barplot indicate the population ID of the samples.
Fig 5.
ASTRAL consensus tree of 121 M. splendida and M. viridis individuals.
All plants were partitioned into nine clades that were indicated by the curved lines and by their population ID next to the tip labels. Node labels are local posterior probability values. Only values of 0.95 or higher are shown.
