DistributionWeakley (2020) includes this "species" within P. prolificum, whereas FNA treats the latter as a subspecies of ramosissimum. There is a single specimen at WCUH from 1927 that was annotated by McMullen as P. exsertum, a synonym of ramosissimum. It needs verification before being admitted to the NC flora.
