From: Reticulate evolution in the Pteris fauriei group (Pteridaceae)
A reticulogram of the Pteris fauriei group, based on the Knox3 sequences. The taxa correspond to the genotypes in Table 1. Maternal contributors of hybrids are shown as red arrows and paternal contributors as blue arrows. Ploidy levels are indicated by symbols: ellipse for diploids, triangle for triploids, and rectangle for unknown ploidy. Different kind of habitats are separated by colors inside symbols. Red or green symbol outlines indicate reproductive mode (sex and apogamy, respectively). Undiscovered taxa have dashed-lined outlines. Alleles of Knox3 and cpDNA haplotypes of each taxon are also presented.
