Fig. 2.

Spatial distribution of clones (genets) in two coastal inselberg populations of Alcantarea: (A) population LNI of A. glaziouana; (B) population RP2 of A. regina. In each graph, colours indicate different clones as identified with eight nuclear microsatellite markers, and stars indicate plants that had unique genotypes for these markers. The two graphs exemplify the spatial clustering of plants belonging to the same clone in populations of these species, which supports the hypothesis of asexual reproduction via vegetative clonal growth rather than agamospermy.
