Figure 1.

Morphologies and key characters of the eight morphs in the Pteris cadieri complex. Two leaves of each morph are shown. The upper leaf is fertile, and the lower leaf is sterile. The key characters include cytotype, phenology (evergreen or deciduous), geographic distribution, chloroplast haplotype, and PgiC genotype. An asterisk * represents an uncertain allele, e.g., genotype X₁*Y means X₁X₁Y or X₁YY. Symbols indicate cytotypes: ○ diploid; ▵ triploid; □ tetraploid. The number in each symbol indicates the morph.
