Figure 2 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 2 - PCA for 5 different taxa of the Tillandsia capillaris complex. Plot of all specimens (100 OTUs) and leaning of the most influential 19 characters represented on the first two principal components resulting from principal component analysis (see Table 2 for abbreviations). References: 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.
