Table 4.

Eigenvector contributions (PC) of each character from the first two axes of the principal component analyses based on all morphological characters incorporating all species (PCA1), the Pediomelum mephiticum-Pediomelum verdiense-Pediomelum pauperitense (MVP) complex only (PCA2), and for the two varieties of Pediomelum megalanthum (PCA3). Characters are described in Table 2.
