The assignment of individual plants to a genetic cluster was unrelated to its spatial position within the population, and Mantel tests showed no correlation between plant distance and genetic distance for populations HUA-W, MOC-W, PEL-W and MAU-W ( P ≥0.197), and a marginally significant correlation for BER-W ( P = 0.09), in which plants were sampled along two transects 1 km distant ( Fig.
