Note
Phanerophlebia (America) and Cyrtomium (Asia, Hawaii) are closely related genera of the tropics, separated on account of their venation. Both genera were described by Presl; Tryon & Tryon (1982) treated the former as Phanerophlebia, but present literature largely retains Cyrtomium for the Old World genera. Kramer in Kubitzki does still only recognise Polystichum; he argues that Cyrtomium and Phanerophlebia have characters that are not sufficiently correlated or constant. A temperate or tropical genus of 9 species, centred in eastern Asia. Until recently treated as Phanerophlebia Presl (Tryon & Tryon, 1982), a name now reserved for the neotropical species of the genus (Kramer et al. in Kubitzki, Fam. Gen. Vasc. Pl. I: 114 (1990)).
