King himself held that: : A peneplain in the Davisian sense, resulting from slope reduction and downwearing, does not exist in nature. It should be redefined as "an imaginary landform."[4] /wiki/Hillslope_evolution
It is argued by T.J. Fair that peneplains also have these gentle concave forms, but W. M. Davis’ view on the issue is not clear, meaning possibly that he might have held that peneplains had very gentle convex slopes.[4] /wiki/William_Morris_Davis
