FIGURE 13 in Morphological and anatomical analyses clarify the species definition of Ceratozamia latifolia Miq. (Zamiaceae) and lead to the description of a new species: Ceratozamia reesii

FIGURE 13. Linear discriminant analysis on leaflet anatomical traits clearly separates the two taxa, Ceratozamia microstrobila and C. latifolia. (A) The two main axes calculated from the variation of traits A–P separates the two specimens of C. microstrobila (mic) and the two specimens of C. latifolia (lat). (B) When consider two groups (mic and lat), a discriminant axis that summarizes the total variation clearly separates the two species. Traits A–P correspond to those listed in Table 4.
