FIGURE 2. Principal Component Analysis of 7 specimens of Elaphoglossum dannoritzeri (filled circles) and 22 specimens of E. mathewsii (open symbols) from Peru (circles), Ecuador (triangles) and Venezuela (squares) based on ten morphological traits with significantly differences between geographical populations (Tab. 1). Lines and grey circles show the vectors of the morphological traits, which are labelled with abbreviations (Pet = petiole, Rhi = rhizome, Sc = scale). The four unlabelled traits on the far right of the graph correspond to color of petiole scale margins, percentage of sclerotic parts in the petiole sales, cover of blade scales, and spore length. PC axis 1 explains 44.9% of the variance (Eigenvalue 4.49) and PC2 17.3% (Eigenvalue 1.73).
