Figure 3 from: Castello L, Galetto L (2013) How many taxa can be recognized within the complex Tillandsia capillaris (Bromeliaceae, Tillandsioideae)? Analysis of the available classifications using a multivariate approach. PhytoKeys 23: 25-39. https://doi.org/10.3897/phytokeys.23.4507

Figure 3 - Principal coordinates analysis (PCoA) for 5 different taxa of the Tillandsia capillaris complex. Scatterplots of the first two axis based on 19 characters selected in the PCA and using the Gower distance (sqrt (1-S)). References: Characters used (see Table I); OTUs: f. capillaris (n=21) =red; f. hieronymi (n=24) =blue; f. incana (n=20) =pink; f. virescens (n=12) =green; f. cordobensis (n=23) =orange.
