FIG. S4. Results from the niche overlap analyses in the space environmental (E) space obtained using the PCA-env method. A. Correlation circle showing the contribution of environmental variables on the first two axes of the PCA-env, and the percentage of inertia explained by the two axes. B ̶ C. Values for the first two principal components obtained in the PCA-env analyses in the studied area. B. Values for the PC1. C. Values for the PC2. Red dots represent specimen records for species included in the clade A (S. imbricatifolia, S. lagunae, S. suffruticosa), while blue dots represent occurrences for species of clade B (S. lechleri, S. parvifolia, S. chillanensis, S. colchaguensis, S. stenophylla).
