Characterization of coastal ‘inselberg’ populations of Alcantarea glaziouana and A. regina with eight nuclear microsatellite markers, including sample size, genotypic diversity (G/N) and Simpson's index to document clonal diversity, and the following diversity and breeding system parameters calculated at the genet level: variance in allele size (Var), allelic richness, expected (H_e) and observed (H_o) heterozygosity, and within-population inbreeding coefficients F_IS
