Private bands are restricted to a single taxon. Marker bands are those found in a relatively higher percentage of one taxon but in a few individuals and populations of other taxa in the hybrid complex (e.g. at least 25% of all populations or individuals in one taxon and only a few individuals in the other taxon). P. centranthifolius (CE) is in section Gentianoides, whereas P. clevelandii (CL), P. spectabilis (SP), and P. grinnellii (GR) are in section Spectabiles. P. × parishii (XP) is the F1 hybrid between P. centranthifolius and P. spectabilis. The close relationship among the species in section Spectabiles accounts for the lower numbers of private and marker alleles compared to the more distantly related P. centranthifolius.
