A number of systematic and phylogenetic studies have been published on the genus involving molecular and other genetic data, but thus far there has not been a comprehensive account. Papers involving Pteridium aquilinum: cpDNA restriction site analysis (Jubrael et al., 1986, 1990; Tan and Thomson, 1990b; Thomson et al., 1995); arbitrarily-primed PCR fingerprinting of nuclear genome (Thomson 2000a, b; Thomson and Alonso-Amelot, 2002; Thomson et al., 2005); ISSR analysis (Thomson et al., 2005); isozyme analysis (Wolf et al., 1988, 1991; Sheffield et al., 1989a, b, 1993, 1995; Rumsey et al., 1991; Bridges et al., 1998; Speer et al., 1999); genome size (Tan and Thomson, 1990a); chloroplast sequence data (Wolf et al., 1995; Speer, 2000); mitochondrial sequence data (Wolf et al., 1995); nuclear sequence data (Thomson et al., 1995, 2000; Wolf et al., 1995).
