DAPC plots of Magnolias from the Caribbean and Mexico. DAPC: Discriminant Analysis of Principal Components. Populations and (sub)species are abbreviated cf. Table 1 and CU: Magnolia cubensis. a DAPC plot of dataset 1 which comprises 340 individuals representing 17 populations, genotyped for all 63 microsatellite markers where possible, including the assumed monomorphic data (See Supplementary Table S2: categories A, B and C). Nine clusters are visualised following the nine species: CU, DOD, DOM, EKM, HAM, LAC, PAL, POR, SPL b DAPC plot of dataset 2 which comprises 340 individuals representing 17 populations, genotyped for all 63 microsatellite markers where possible, excluding the assumed monomorphic data (See Supplementary Table S2: categories A and B). Eleven clusters are visualised: CU (behind SPL), DOD, DOM, HAM, GRA, LAC (population), MAN, PAL (behind POR), POR (behind DOM), SPL, YAJ. C DAPC plot of dataset 3 which comprises 260 individuals representing 13 populations of the 8 taxa of the section Talauma subsection Splendentes (See Table 1: Class. = TAS), genotyped for 10 microsatellite markers (See Supplementary Table S2: marker names indicated with an asterisk). mix1: all 40 individuals of DOM and 3 individuals of SAL. mix2: all 40 individuals of PAL and 1 individual of PIC. Nine clusters are visualised: GRA, MAN, mix1 (behind PAL), mix2, PAL, PIC, POR, SPL, TOP
