Abstract

Abstract Restriction site mutations in the chloroplast DNAs from members of the fern genus, Phanerophlebia, and some representatives of Cyrtomium and Polystichum were used to elucidate phylogenetic relationships within and between these groups. Evidence is presented against the hypothesis that Phanerophlebia was derived from Cyrtomium; rather the two genera appear to be convergent segregate genera that arose independently from Polystichum. The chloroplast DNA mutations also provide information on the maternal parentage of several tetraploid species
